How to setting ikev2.conf on docker image for support sctp protocol about docker-ipsec-vpn-server HOT 1 CLOSED

@andy112233445566 Hello! Thanks for providing the details in this issue. I am not familiar with SCTP, but it looks like SCTP might have some issues with IPsec VPNs [1]. I did a quick web search and this article [2] might help your use case. More specifically, in order for IPTables in the IPsec VPN container to properly forward SCTP traffic, you'll need to load a kernel module:

modprobe nf_conntrack_proto_sctp

Restart the Docker container after that. Re-connect and check if the issue is resolved.

If loading the kernel module on the Docker host doesn't help, you can try loading it from inside the container.
