Hi Cullen, (cc:ing dccp mailing list as well)
The dccp/udp port issues were discussed in the DCCP WG some time ago. With the source port one problem is that a NAT could change the UDP port but not the inner DCCP port. There were opinions for keeping the two port spaces separate, to support tunneling scenarios through a well-known UDP port at the server end. - Pasi On Mar 2, 2011, at 11:35 PM, Cullen Jennings wrote: > I'm wondering what would be the downside of saying the UDP source / dest port > had to match the DCCP source and dest port?
