Yikes, this sounds like it could work. I was thinking of having the gw run a
script with a known Private Address Pool (since each ISP has a known number of
address's) and try each address until a connection is made. With a class C of
address, or more, that could take up some time. The idea of forwarding on the new
negotiated address/domain name seems like a simpler solution.
With a smaller pool of address's maybe a pearl script would be faster.
Thank you for your input, 73
