(usr-tc) IP filter example
I am wanting to filter outbound traffic from my users so that my core is protected (only allow http to webserver, smtp/pop to mail server, dns to nameserver, no telnet, etc)............... If anyone has an example IP filter that would be really cool, so I could have something to work off of. Also if you could show me how you applied it to users in RADIUS that would be good too.

U>Appreciate it, U>Brian Brian, Here you go: Filtername - email.in #filter IP: 010 AND src-addr = 199.178.136.0/24; 020 ACCEPT dst-addr = 199.178.136.0/24; 030 DENY; Fintername - email.out #filter IP: 010 AND src-addr = 199.178.136.0/24; 020 ACCEPT dst-addr = 199.178.136.0/24; 030 DENY; Then in RADIUS in the FRAMED_FILTER_ID field we put "email" as the filter. In the case of the above filters the IP pool, webserver, and E- mail server all reside within the same class c address.
