Hey guys
I am confused with the packets i captured using ethereal. i am able to connect to my office network from home. we are running MS small business server 2000 and a Cisco 2600 router configured for NAT. I tried to capture packets using ethereal on my server (192.168.0.35) and my router with public IP of 208.57.52.216.

I try to telnet from my server to router (208.57.52.216) with different ports. The ethereal ouputs look like this:

192.168.0.35 - SYN
208.57.52.216 - RST, ACK.
and no more results neither from server nor router

Can anybody tell me, what is going on in this and how to approach this.

I would greatly appreciate your inputs.
thanks
ganesh

This is the expected output for trying to establish a connection to a port that is non listening. Did you establish a successful telnet session while you were sniffing?
