Hello,
have you ever heard for RADWARE solution for that problem?
Some RADWARE box can check distance to destination via both ISP's and makes
decision from what IP address range have to get address for NAT (of course,
customer have to have two ranges of addresses). If connection via one ISP
failed, all traffic will be rerouted via another using IP address from IP
address range of that ISP.
