		rjsw on Aug 7, 2020 \| parent \| context \| favorite \| on: Exploiting Android Messengers with WebRTC The comments in the Firefox WebRTC code state that this is because firewalls can't do NAT of SCTP connections. I'm part way through adding this to the firewall that I use. On FreeBSD, WebRTC implementations could use the kernel stack as it implements SCTP-in-UDP (RFC6951).

For WebRTC SCTP is over DTLS (which is over UDP) so I don't think that would work.

Never done 'native SCTP' before so I don't know for sure!
