(eta salutation, which keeps getting eaten.)

Hi, all.

I see a bunch of related questions, so I'm hesitant to ask, but:

I have a situation where I have a Sonicwall NSA220 serving as firewall/router for two internal subnets to two external WAN connections. In some locations this is two separate ISPs. In others, it's the same ISP but with multiple circuits.

The problem is that one ISP has been unable to provide unique subnets for each WAN interface.

Is there any possibility that I might be able to bond the two WAN interfaces into a single virtual interface, and then use source-routing to get internal subnets communicating out the appropriate physical interface? Or even just use traffic-shaping to give each internal network appropriate shared bandwidth? I haven't found anything in the docs, but it seemed like it might be worth asking.

Thanks for any help! -Steve.
