I have read some recommendations on combining a stateful firewall with divert,
and http://nuclight.livejournal.com/124348.html (the latter is in Russian).
Do I understand correctly that it is (mathematically?) impossible to
use the two together without also using "skipto"?
If we consider a simple example below, how would you replace the 600th
rule for a stateful one?
00100 divert 8668 ip from any to table(1) out via rl0
00200 deny log logamount 100 ip from 10.0.0.0/8 to any out via rl0
00300 deny log logamount 100 ip from 172.16.0.0/12 to any out via rl0
00400 deny log logamount 100 ip from 192.168.0.0/16 to any out via rl0
00500 divert 8668 ip from table(1) to any in via rl0
00600 allow ip from table(1) to any in via rl0
00700 deny log logamount 100 ip from any to 10.0.0.0/8 in via rl0
00800 deny log logamount 100 ip from any to 172.16.0.0/12 in via rl0
00900 deny log logamount 100 ip from any to 192.168.0.0/16 in via rl0
65535 allow ip from any to any
Thank you in advance for any input.
