DCCP and NAT
Dear Gerrit,
do you remember me? I wrote you about dccp_modprobe. I have resolved that prolem, but now I have another.
My ISP (Vodafone Italia) use the NAT, so it's impossible to use dccp protocol in a connection between two host that support DCCP. Have you suggestion in order to resolve this problem?
Thanks,
Giuseppe

Since you are most likely using ISP NAT equipment and since only the Linux NAT at the moment supports DCCP, the only way around this is tunnelling. Tom Phelan has written a draft for UDP encapsulation of DCCP

and provides software (DCCP-TP) with support for UDP tunnelling:

Is it possible for you to use Linux NAT instead of the Vodafone NAT? If yes, we have developed an alternative NAT traversal solution which does not require tunnelling. Will put information out about this later.
