Message-Id: <47CEF714.708@variadic.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: dccp@vger.kernel.org I'm running into a need for encapsulation due to various providers mangling (mandatory NATs on local EVDO service) or dropping (AT&T Yahoo DSL residential service (but business service works it seems)) DCCP traffic. I figure DCCP-NAT[1] support in the stack is exactly what I need, but AFAIK it's not implemented yet (only in DCCP-TP I think). Is there an existing solution at the moment to add the encoding, or near term plan to implement it? If not, would it make sense to route the traffic into a tun device that adds/removes the encoding? Is there a better way to get the DCCP packet before it's sent than having an extra service/interface like that? I'm not familiar enough with the kernel layer to implement it there in reasonable time which is why I'm looking at doing a quick hack in userland.
