Using LTM for network forwarding

Yes, the F5 can reach both the internal server and the public internet cloud. So assuming we have routes on our internal router for all these public cloud networks pointing at our F5, I'm trying to understand all the various forwarding configuration options I've got. It sounds like I could create a forwarding VS for each corresponding public cloud network and enable SNAT. Painful, but possible. Based on a comment above, it sounds like I could apply an iRule to my existing wildcard VS and SNAT traffic with a destination of these public internet clouds. I don't want to do this either, but possible. Are there other VS types or properties on the F5 that would allow this internal server to get out to a public network?

If the connection was point-to-point, this would be simple. The kicker for me is that the destination is a network, not a single endpoint. That throws a non-networking guy like me for a loop.
