Hi Michael,
Thank you for your reply. Yes your right, my question is on SCTP/DTLS implementation running on a kernel implementation but I couldn't find anyother forum specifically for that.

Using Wireshark, there was an INIT from the client [Src Port: 29099] to the server [Dst Port: 23232]. The next captured packet was ICMP with info "Destination unreachable (Port unreachable)" and the ICMP originated from the server end.


Best Regards,
Promise.

Hi Promise.

this list is for supporting the sctplib implementation. Your questions
seems to be related to the SCTP/DTLS implementation running on a kernel
implementation. So I'm not sure if anyone can help you here.

You might want to ask Robin, who implemented the stuff.

Are there any SCTP and/or DTLS packets being exchanged?

Best regards
Michael
