Network traffic management

[dmalamba]

exchange server 5.5. I have implemented NAT

and access-list to permit mail through the

NAT interface. What stratles me is that the

64 k line seems to be at peak use all the time

and I dont believe this is the mail traffic

which is causing this. How can I check traffic typeS

passing through this interface and their port numbers

so i can block them? i.e only accept pop3 and smtp and probably www.

If you have a laptop and open switch port, you can also download ethereal - shareware protocol analyzer, which can "look" at traffic via spanport/port mon
