Question about Zyxel ZYWALL 35 Firewall
I don't know if this will help because I don't see what you and seeing but here is an idea: In every routing scenario I have experienced, you must specify a default gateway with a specific IP address. 0.0.0.0 only points to the device itself, not the other WANS. The gateway IP addresses should be statically assigned. If there is DHCP involved, insure that the gateway address is not part of the DHCP scope but in an excluded range of reserved addresses. For SMTP to work the gateways (and you should have 2 or 3) must be properly configured and TCP port 25 enabled.
