Yeah, I don't know what your problem is with Mailwasher. Sygate should be
set to trust the device IP of the router and should not be blocking it.
Since Mailwasher is making the requests for solicited traffic from behind
the router and the PFW solution, then they both should allow inbound
traffic to Mailwasher. I doubt that the router is causing the blockage
and you may want to drop Sygate and see what happens, since the machine
is protected by the router. I use Mailwasher and have not had any
problems due to the router.
