In terms of adding routes back to the VPN subnets, that is what I want to do, but that is where there is a tricky problem...

When an individual client connects to either VPN server, it will get the exact same IP. This is done so that software (like NFS) will be able to basically handle a client moving from one VPN to the other if

Hi Erich,

You didn't say whether you are aware of any way to route back to the two VPN hosts other than the source NAT that I described. Even if I don't use this for NFS failover, dealing with one set of addresses rather than two will be helpful.

Oh, I am sorry. Using two distinct address pools makes routing childs play. Just add both routes. The only thing you will be missing is seamless hand over. If it is a prerequisite, then this probably won't work.
