Any hardware/software routers that support Full Cone NAT?-Collection of common programming errors

i’m trying to get Teredo to function on my machine.

Most routers, it seems, refuse to forward packets from any host other than the one i specifically connected to first. Teredo requires full Cone NAT in order to function.

Does any router, hardware or software, allow full cone NAT?

Is this an oversight by the designers of Teredo that nobody, in practice, can use it?

• D-Link
• Linksys
