R3d The reason is quite simple but i can't fix it, when a request arrives from sk0 the server tries to answer through the gateway, however the packet is routed to 200.14.xxx.1 (fxp0) then the client never receives ACK
I realize that this is about 2 years late, but freebsd will only route to the locally connected lan on the nic that the traffic originates from. If it's from a lan other than the nic's local lan, the return path will be the default gateway. To have traffic route the other nic, you'll need to set up routing protocols or static routes.
