Hi everyone,
I have been reading pages and pages of information on how to monitor traffic on a cisco router, but it's all very confusing. Here is what I am doing:
I telnet into my router I enter privileged mode I type "terminal monitor" so I can see the debug information
-- here's where I am stuck. I want to see all traffic that is exiting port 24. I need to see source IP (which computer on my network sent it) and Destination IP (wherever that is on the Web). Port 24 of my router is connected to my firewall, and my firewall is connected to the web. Port 24 does NOT have it's own IP address.
I create access-list 123: "access-list 123 permit ip 192.168.111.0
0.0.0.255 any" where 192.168.111.0 is the subnet of all my PCs on my network.I then enter the command "debug ip packet 123"
Now I see ALL traffic. entering and exiting the router. How do I limit the traffic I see to Port 24 ONLY? In the outbound direction only?
Thanks.
