I'm working on Pix firewall and I just want to talk about the "conduit"
notion.
A conduit open a way between 2 subnets separated by a firewall. After
you have created the conduit, you can create rules regarding this
conduit.
Maybe there is no conduit(I don't know the name used by Gardian Pro for
this notion)between LAN1 and LAN2. And so that's the reason you can't
have information from LAN2 to LAN1, even if you allowed everything on
the firewall.
