Lynwood, Thanks for the info. It must have something to do with the mega version of DD-WRT that you are using. I am using the standard version, and it does not pass, even with the VPN passthough options enabled. I see the mega version has IPV6 support. Since that is usually tunneled, I suspect that is what makes it work for you. - Question for anyone. Is there anyway to use the ampr.org name service as a dynamic dns? For my IPIP gateway, and other ham radio related things, I have have been using dyn.com to provide a dynamic dns name. With the new http://dyn.com update policy,, makes me think the ham community could use a dynamic dns of their own.. anyone?
