Question: I am trying to create a RAS server in XP Pro. The idea is to log in to this server via a dialup connection. I have set up a new network connection via the New Connect Wizard in XP - according to [this tutorial](https://web.archive.org/web/1/http://articles.techrepublic%2ecom%2ecom/5100-10878_11-5034594.html) on techrepublic. 

I am sure that the modem and the connection is working, I have tested it.

However, I want to monitor incoming network traffic on this connection. So I thought I would use Wireshark. The problem is that Wireshark does not list this incoming connection on the front page. It lists all my other network connections, ( e.g. my ethernet connection ) but not this one.

Whats the best way to monitor traffic on this connection?

Answer: 
Wireshark should be able to capture the traffic on your connection. I would check the protocol you're using for communication and make sure that Wireshark is monitoring those protocols. Also, I would make sure that Wireshark is actually capturing traffic on your dial up device. It sounds like it's currently monitoring your NIC card, not your modem.
I recently found Microsoft Network Monitor and it has ability to sniff on dialup adapter with Vista or Win7 as OS. Works great!
