 > Can't reproduce on both 9.0 and 8.3. Could you test on them please?
 
 I've just testet 8.3-PRERELEASE and problem is still here.
 In my current setup, the router based on 8.3-PRE has 3 interfaces:
 
 - vr0 is LAN
 - ng0 is primary uplink (default route points to ng0)
 - vr1 is secondary uplink.
 
 The very first lines of ipfw ruleset are:
 
 ipfw add 10 fwd G.G.G.G ip from any to 1.1.1.1 in recv vr0
 ipfw add 15 allow ip from any to 1.1.1.1 in
 ipfw add 20 count ip from any to 1.1.1.1 out xmit ng0
 
 Here G.G.G.G is gateway address of secondary uplink,
 so route to G.G.G.G points to vr1. And I run "ping -c1 1.1.1.1"
 from LAN while running "tcpdump -np vr1 host 1.1.1.1".
 
 tcpdump shows me that rule 10 works and ICMP packet goes out via vr1.
 But the packes still matchs rule 20 - that's the problem.
