Hello list ! It may sound noobish but is there a way to filter traffic based on regular expression matching ?
My os is Centos 5 and i'm currently using shorewall 3.4.2-6 installed from rpm. The issue i have is that yahoo messenger keeps using nonstandard ports to connect. Lately i blocked yahoo messenger and it connects to port 25 to get outside the corporate network. I could block the ssl port but it will break ssl sites and i need to block only certain hosts that it connects to. Regular expression matching of hostnames that the application connects to will help me get this policy working whatever ports will this application use, i guess. I use a local http proxy but the messenger application gets around it because i allow mail ports (25, 143, 101) to access the internet from the lan. Any suggestions will be appreciated ! ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
