Hi IPFW mailing list,

I was wondering if its possible to filter on transit traffic between two
VLAN interfaces with ipfw using interface names (not subnets).
Right now I see traffic like this on a certain subnet, VLAN 214. Lets say I
have another interface, VLAN 1, and I want to deny traffic from VLAN 214 to
VLAN1,

I was thinking that; add 1212 deny ip from any to any in via bridge214 out
via bridge1 would work, but it doesn't.
 Any thoughts or how to achieve this in the best way? This machine is also
the router.

Regards
Dries
