Re: Blocking MSN Messanger ports

gw#sh ip inspect sessions | include 1863
 Session 237F2E0 (196.7.x.x:1029)=>(64.4.13.147:1863) tcp SIS_OPEN

if I kill 1863, my msn dies. you sure it moves to the next available port?
are they using the standard msn or another client that can speak to msn
servers?

Regards
