I have a Firewall with more than two interfaces (two internal network
interfaces and one internat interface). When I open a rule to allow one
internal network to browse the internet, buy allow.
 10.10.0.0/16 -> 0.0.0.0 port 80
as a side effect, I opened http rule from one internal network to the other
internal network as well.

I think it will be a good idea to and an outgoing interface check into the
rule. (not the same as the fastroute interface)

How about try a routing attempt to verify if the packet will leave the
Firewall on the intended interface. For those stateful rules, such
verification is only needed once during state creation. Wonder if this has
been done on 4.x version?
