Hi,

Configure the command "reverse-route injection" under "crypto 
dynamic-map vpnusers 1"

On the otherway, you can clean up your config and use Cisco SDM 
(Security Device Manager) to configure the Easy VPN Server.

Cisco 837 and Cisco VPN client wierdness.. any ideas?
With my current configuration I can VPN connect from anywhere on the web and authenticate as a local user with an 837 router. Once auth'd the VPN client is allocated an IP from the vpn pool. From a VPN connected laptop I can ping any address on the LAN and any other machine on the LAN can ping the IP the VPN client has been allocated. However I can't access all resources via all protocols on all machines. This part is inconsistent and has me baffled. e.g. from a VPN client I can mount SMB shares on 192.168.16.250 but I can't see the webserver (:80) on the same IP). From a LAN connected laptop I can see the webserver running on the VPN client (192.168.17.x:80). However the VPN client can't see a webserver on the same LAN connected laptop (192.168.16.10:80). This is my first ever contact with Cisco gear and while i'm quite chuffed with getting as far as I have on setting this box up.. i'm now way out of my depth on working out what the problem is. Any suggestions would be greatly appreciated! Client s/w is v4.6 (0045) on Mac OS 10.3.9 sh version reports: IOS (tm) C837 Software (C837-K9O3Y6-M), Version 12.2(13)ZH4 Router config (security edited) is cut/pasted below: ! version 12.2 no service pad service timestamps debug datetime msec service timestamps log datetime msec service password-encryption ! hostname xxxx ! logging queue-limit 100 no logging buffered enable secret 5 xxxx ! username xxxx password 7 xxxx username xxxx password 7 xxx...

Remote access fun with Cisco 837 and locally auth'd Cisco VPN client
Hi Folks, Through a fair amount of googling, usenet trawling and blind hacking i've managed to get a Cisco 837 connected to the net. I'm now able to browse the net 100% and the router has several port forwards setup to expose a webserver along with RDP and Windows VPN services from a Win2k3 server. Now.. while all of those work, just having windows VPN and RDP ports exposed to the world at large isn't that secure. I'd prefer to use the 837's VPN capabilities to access internal LAN resources securely from anywhere on the net when i'm in the office or away travelling. My ISP (Nildram in the UK) allocates the router a static IP address by DHCP. The LAN IP range is 192.168.16.1 255.255.255.0 with the router on 192.168.16.1. The Win2k3 server that I need to access is 192.168.16.250 and a LAN connected laptop has a static dhcp allocation (from the Win2k3 server) of 192.168.16.10. I'm testing remote access with the Cisco v4.6.00 (0045) VPN client for Macintosh by dialing the internet on another laptop that's not connected to the internal LAN. With my current running configuration I can connect from anywhere on the web and authenticate as a local user with the 837. Once auth'd the VPN client is allocated an IP from the vpn pool. From the VPN connected laptop I can ping any address on the LAN and any other machine on the LAN can ping the IP the VPN client has been allocated. However I cannot access resources via all protocols o...

VPN Connection Problems between Cisco PIX 506E and Cisco VPN Concentrator 3005
Hello all, I got a problem with a vpn connection from a cisco pix 506E to a cisco 3005 concentrator. The problem is that the lan on the pix is also used to another remote side. so I tried to activate NAT on the pix to translate the ip adresses of the network. after that I entered the information at the concentrator which are nessassray for the lan-to-lan connection. But I did not get a connection. I tried to ping the outside address of the pix but I did not get a reply. I post the output of the logfile for that connection below: 29437 02/15/2005 14:25:21.890 SEV=4 IKE/41 RPT=43758 213.183.66.179 IKE Initiator: New Phase 1, Intf 2, IKE Peer 213.183.66.179 local Proxy Address 192.168.0.0, remote Proxy Address 213.183.66.179, SA (L2L: to PIX) 29507 02/15/2005 14:26:02.300 SEV=4 IKEDBG/65 RPT=36896 213.183.66.179 Group [213.183.66.179] IKE MM Initiator FSM error history (struct &0x3b7510c) <state>, <event>: MM_DONE, EV_ERROR MM_WAIT_MSG6, EV_TIMEOUT MM_WAIT_MSG6, NullEvent MM_SND_MSG5, EV_SND_MSG and here is the config of the pix: PIX Version 6.3(4) interface ethernet0 auto interface ethernet1 auto nameif ethernet0 outside security0 nameif ethernet1 inside security100 enable password 8Ry2YjIyt7RRXU24 encrypted passwd 2KFQnbNIdI.2KYOU encrypted hostname Cisco-Firewall-VPN domain-name pk-intern.de clock timezone CEST 1 clock summer-time CEDT recurring last Sun Mar 2:00 last Sun Oct 3:00 fixup protocol dns maximum-length 512 fixup protocol ftp 21 fixup pro...

VPN - Cisco IOS <-> VPN Client
Hello everybody, I have tried to set up a VPN connection from Cisco VPN Client (4.6.00.0045 on Win XP Sp2) to Cisco Router 2621 (64MB RAM/ 16MB Flash) - with enterprise IOS 12.2. When I map a crypto map to the interface ( crypto map CRYPTOMAP to serial 0/0.1 ) - the nat stopped working and I havn't got a remonte connection to my router and other services behind the router. When I got to the LAN I was able to connect to router via ssh. Then I removed crypto map on Serial 0/0.1 and nat starts working but I haven't got a VPN connection :( I don't know what is wrong. I have studied Cisco materials and some other configs without any ideas. Would You be so kind and help me with this configuration ? Thanks a lot. ! !

Cisco VPN Client 4.6.00.0049 to Cisco router 12.3.8T5, ACL's ?
Hello, I regulary implement Cisco routers for our customers. About a year ago the demand for being able to VPN rose, and after some TAC calls I succeeded in configuring this on a Cisco router. At that time it were mostly 1700 series routers (running IOS 12.2.15Tx) with the Cisco 4.0x VPN Client. That configuration has been implemented at numerous sites since then, and works perfect. But since we started implementing routers with IOS 12.3.8Tx and the Cisco VPN Client 4.6.00.0049 I'm seeing differences in how the routers act in processing the VPN traffic. In my original config I ne...

IPSec VPN problem with a CISCO C827 ADSL Router and a Nortel Contivity VPN Client
Hi, I'm a newbie and I'm facing a problem. I need to connect to a VPN, through IPSec. I have a CISCO C827 ADSL Router. I'm using Nortel Contivity VPN Client. If I connect by a modem to any provider, it works great. If I try to do it through the C827, no way. It says on my side : Server not responding, and on the server side : Client not responding. Anybody knows how I could/should configure my router to have it work ? Here's a piece of my configuration : ip dhcp pool maison network 192.168.1.0 255.255.255.0 default-router 192.168.1.254 dns-server xxxxxxxxxx xxxx...

L2TPD/Cisco VPN client problem
Hi, I'm using Cisco VPN client 3.7 under Mandrake 9.1 Linux to connect to a VPN server at my work. This should be done through an L2TP tunnel provided by my ISP. However, after initial connect the connection fails. Looking in the syslog I found the following error: kernel: unknown mac header length. I don't really understand what this error means, so I'm not able to solve this on my own. Any ideas as how to solve this problem? Bass ...

Cisco VPN Client AddRoute problem
Hi, When connected to the VPN, it hits the RADIUS server fine and gets connected but fails to add the route and therefore, I cannot access anything inside the network. I get this error in the logs. AddRoute failed to add a route: code 87 I cannot find anything online that discusses this error with someone actually getting connected and getting ONLY this error. I get it on the route to my organization's one subnet and I get it only SOME of the time. I can still access the Internet (using split tunneling). Any ideas? Again, it works most of the time, but when it doesn't work, dis...

Problems connecting with Cisco VPN client
First, let me say I'm in not very well versed in network issues. I'm trying to connect to a client's network through the Cisco VPN Client which they sent along with the configuration file. My network is behind a Linksys router. I have 2 XP machines (desktop and laptop). The laptop connects without any problems, but the desktop will not. I've attached the Cisco log files for both connections below. Their network administrator tells me that the reason I'm not connecting is because of authentication, but that doesn't make sense since the laptop can connect without any issues. My guess is that there is a setting issue of some kind on the desktop which I can't figure out. I do not use XP firewall, have Norton AV and have disabled the Worm Protection (though on the laptop it is not disabled and works fine). Any ideas/help would be greatly appreciated. If you need me to post additional info, please be considerate of my limited knowledge when asking.

Cisco newbie with a routing problem with Cisco 2621
We recently changed providers, which has caused all sorts of headaches for me. The new ISP does not provide routers, but the sales rep found us a Cisco 2621 and someone to program it. Seeing as how I have had to have the programming corrected a couple of times already, I suspect my routing problem might stem from the Cisco. We have 4 concurrent Class C addresses, and all but one of the Class C's are working fine. The last one, xxx.xxx.208.1, will not allow access to certain (not all) websites or ftp servers. I have eliminated the DNS and DHCP on my end as the culprit (I believe), so I'm stuck with thinking the Cisco may be the problem. I'm at a complete loss here, as I'm not a Cisco person, and really need some direction. Does any of this make sense? I have posted my config below, if it is any help. Thanks for any help anyone can offer me!! Rick The current config is below: Using 1104 out of 29688 bytes ! version 12.3 service timestamps debug uptime service timestamps log uptime no service password-encryption ! hostname INET ! boot-start-marker boot-end-marker ! enable password xxxxxxxxxx ! memory-size iomem 20 no aaa new-model ip subnet-zero ip cef ! ! ! ip name-server xx.x.xx.xx ip name-server xx.x.xx.xx ! ! ! ! interface FastEthernet0/0 description connected to xxxxxxxx ip address xx.xxx.xxx.xx 255.255.255.252 no ip proxy-arp duplex auto speed auto arp timeout 30 ! interface FastEthernet0/1 description connected to DHCP ip address xxx.xx...

Cisco 831 VPN to Cisco 3030 Security
I'm planning on deploying Cisco 831 VPN routers and having them connect to the Corp office over a DSL connection to a Cisco 3030. I'm curious how others handled security to keep unwanted users out. This of course assumes you have split tunneling off and there is a branch office type setup. I'm trying to figure out how to have some sort of login/password challenge to keep one of our remote users family members from plugging in a laptop or similar system and connecting to our network. The DHCP will only serve up one usable IP address from the 831 but you never know. Any help is m...

Cisco VPN client OK
Hi, I have my PIX set up allowing VPN clients in. A Cisco VPN client (v4.0.3D) can get in OK but a Checkpoint client (R56 Build 311) can't. The Checkpoint client never appears to hit the outside interface of the PIX as no debug info appears when he tries to connect. I hardly need to deinstall my Cisco client sw beofre firing up the Checkpoint - do I? TIA, Ned ...
