Hi All

Over the holiday I upgraded to:
Netfilter v1.4.14
OS 3.6.10-2.fc17.i686

I have the following in my rules:
-A PREROUTING -i p1p1 -p tcp --dport 4800 -j DNAT --to 192.168.1.253
...
-A FORWARD -i p1p1 -o em1 -d 192.168.1.253 -p tcp --syn -m connlimit --connlimit-above 1
-j LOG --log-prefix " MultiIP "
-A FORWARD -i p1p1 -o em1 -d 192.168.1.253 -p tcp --syn -m connlimit --connlimit-above 1
-j REJECT --reject-with tcp-reset

With the old OS - I would see the above log entry some of the time and assumed that the
packet was dropped.

With the NEW OS - I am not seeing anything.

conntrack shows incoming and outgoing ( conntrack -L ) but the filter is not logging or
rejecting any of the connections.

What am I missing?

Oh, folks connect on tcp 4800, then get a UDP port from the endpoint application.  I can
view the endpoint application and see multiple connections from the same IP.

Thanks and Happy New Year!
