Contact me if you're interested. Compatibility Test Results I am testing the compatibility of this approach with several NAT implementations. Thanks to Nevod for their early help doing compatibility testing. Win98 SE contains Internet Connection Sharing software which traces its origins back to NAT1000, so it should work fine. SyGate - fully compatible.
Current releases are probably also fully compatible.
Linux IP Masquerading - kernel 2.2.1 and later should work fine. See Juanjo's page for the patch for earlier 2.1 kernels. WinNAT - their current release works fine. Vicomsoft Softrouter Plus Vicom has since released a version that should fix the problem, but I haven't had a chance to test it. Be sure to read their doc all the way through before using their Setup Assistant.
