Sometimes I have to set up a LAN inside a pre-existing NAT'd LAN and
traffic from the inner LAN (B) does not make it to the Internet or even
to final, external interface (4).
+-------+ +--------+
LAN B ---+ 1 + + Box2 +
+ NAT + + 4+---> Internet
+ 2+--LAN A--+3 NAT +
+ Box1 + + +
+-------+ +--------+
What kind of generic change is needed in PF to get from LAN B through to
the outside?
Setting the IP range for LAN B to match those of LAN A is one option,
but has to be done each time and also may run the risk of collision on
some subnets.
