Description

using "divert port (max-packets 8)"

This causes pf to throw a syntax error since divert and max-packets don't appear to be valid in this version of pf.

Attached my config.xml. The l7 portion results in the following /tmp/rules.debug line:
pass in log quick on $GUEST inet proto { tcp udp } from 192.168.2.1/24 to any divert 45164 tracker 1412311190 keep state ( max-packets 8 ) label "USER_RULE"

This change seems to only address half the issue. The max-packets option still seems to be missing or is that something that isn't done in the pfsense source? If so I can test it when the next snapshot is built.

I already added max-packets to the parser, please try new snapshots that are already available.

This seems to have corrected the syntax issues. There appears to be some performance issues now. I understand some performance hit is to be expected but this pegs my 1GHz CPU to 100% with a single machine loading web pages or requesting DNS. I also noticed that the rules created from the rules.debug don't have the max-packets in them which might explain it.

Its expected and resolving this is not in plan for 2.2.

Also that is not what this ticket is about.
