Multiple external network wondering about routes

[Patriccc]

Have an 1800 Spark and have it set up with an external interface to the internet. But if I want one more external network tagged on the external interface.  Can i make it so that traffic entering that network is routed out again on that network instead of the default gateway that is on the first network. So routing management of traffic?

AFAIK, you can use both WAN and DMZ interfaces as external, with ISP redundancy setup. Depending on whether you use central or local management, look into the "Configuring Internet Connectivity" chapter of your admin guide.
