I have to stand somewhat corrected.
create a filter "internet.out" Contents: three lines for each net block you have:
permit 1.2.3.4/20 tcp permit 1.2.3.4/20 udp permit 1.2.3.4/20 icmp
The more appropriate format would be: permit 1.2.3.4/20 0.0.0.0/0 tcp permit 1.2.3.4/20 0.0.0.0/0 udp permit 1.2.3.4/20 0.0.0.0/0 icmp You are *supposed* to use a src/dest netblock pair, though I have set up and used w/o a dest address and it worked.
final line to log (optional) MUST COME AFTER permit list for netblocks: deny log
If you choose not to log, then you need a line: deny Otherwise that which falls through isn't denied, obviously. Doing router filters while fatigued is often a problematic process. Try and work on them when you aren't so tired, unlike me when I sent my first mail 8-) -george william herbert gherbert@crl.com
