This is the filter I use to limit users to our local e-mail server and
nameserver.
permit udp dst eq 53
permit tcp dst eq 25
permit tcp dst eq 110
deny
It is loaded into the filters table of each of the PM2e's and is called
"emailonly.in"
This is how the filter is assigned to the users
username Password = "password",
User-Service = Framed-User,
Framed-Filter = "emailonly",
Idle-Timeout = 300,
