Hi,
I have a question regarding ipfw fwd rule.
I'm using FreeBSD 5.4-STABLE and running on it bridging firewall using ipfw.
Now my question comes:)
Can I use ipfw fwd rules against traffic coming to one of the bridged
interfaces?
I would like to forward some packets (which are destined to port 110) to
some other router through third vr0 interface.
This is because we have 2 upstream providers and one of the providers is
filtering some ports and
I would like to forward such packets to the other provider.
In other words I would like to do something like:
ipfw add fwd z.z.z.z ip from x.x.x.0/19 to any dst-port 25,110
Is it possible? Should z.z.z.z address be included in the routing table of
the machine or it doesn't matter?
I appreciate if somebody can give me some direction and advice.
thanks in advance,
Ganbold
