I'm on a ADSL broadband net connection and have a static IP Address.
When I connect my Laptop to dialup connection on a different phone
line and send e-mail from it the e-mail header contains the static IP
Address of my ADSL internet connection.
I can see in header
The AA-XX-YYY-ZZ is my static IP Address with . replaced by - (I
how and why they replace . by - in e-mailheader) on ADSL net
I wonder how on the Earth the static IP Address of ADSL Internet
connection from different telephone line all together is visible in a
dialup internet connection? In dial up obviously it is a dyanmic IP
I use a different SMTP Server (Which is not hosted on myStatic IP
Address) to send e-mail from dialup connection.

Your operating system is still probably routing your outbound IP traffic
through your DSL connection, even if you dialed in through a modem.

Static .vs dynamic IP addresses We are looking at getting DSL and the less expensive one from SBC only
has one dynamic IP address. We will be using 2 computers on this
connection (networked). My son may be interested in playing games. Will
this work? I read somewhere that some games require a static IP. To get
this is about $70 per month as opposed to about $30 for the other. What

Mails treated as spam because of dynamic IP address Hello Folks,
1. Our company has a private network and has an internet gateway
machine. We use NAT.
2. The gateway's internet IP address is dynamic.
3. Our mail server is on the internet and runs sendmail
4. Our email clients (Tbird, Outlook) point to that mail server as
their SMTP server
What happens is that sometimes the dynamic IP address is listed on DSBL
and our mails are rejected. My suspicion is that this is because
sendmail adds headers like:
Received: from [192.168.0.8] ([59.W.X.Y]) (authenticated bits=0) by ...
and the 59.W.X.Y dynamic address is the gateway address and is on...
VPN between peers with dynamic IP address and dynamic DNS Hi,
I have 2 Cisco 8xx routers, both with an ethernet (internal) and ADSL
(external) interfaces. The IP address given to the ADSL interface is
dynamic, negotiated via PPP to a dialer interface, a configuration from a
Both external dynamic IP addresses are known with a fully qualified domain
name via dynamic DNS that I set up already.
Now I would like to set up a VPN between these 2 routers to connect the 2
internal networks together: I set up the VPN using their IP addresses
(crypto policy, crypto transform-set, crypto map) and it works like a charm
until I reboot the rou...

static ip address changes I have a laptop running Windows XP SP2 with all updates installed.
Only the wireless network connection is enabled and I have set a
static IP address. However the IP address consistently gets
changed and always to the same new IP. It was suggested that
another computer on the subnet is doing a reverse ARP that is
making this happen but I haven't been able to find out if that's the
case. Any ideas as to what might be going on and how to prevent

I try to do it in C#.

firewalls and a static IP address I have a situation where multiple customers allow remote access through
a firewall via SSH, Remote Access Cards, etc. All the customers allow
access ONLY from the same specific IP address.
My question is, is there a hardware device, router, etc that would
allow a nomadic user via a laptop to connect with; which then allow the
laptop to have the same external IP address as the device/network
(which just so happens to be the IP address the customers allow through

which ip address triggers dialing out? Hello,
Rolf here, from Utrecht, The Netherlands.
Our cisco 4000 has 4 bri ports, which are mostly used by our developers to
deliver support in France and Spain.
Lately, I discovered that connections are made(and remain up for the default
120s) a lot of times including during the night(!) . The developers keep
their machine running during night times and I think there is a process on
one of these machines which causes the call to Spain.
I am trying to find out which machine is responsible for keeping this line
