problem setting up SCTP client-server in linux

Question

Hi,

I'm trying to get SCTP to work. I wrote a simple client and server and tested it with localhost(127.0.0.1 as server). it works perfectly, the server bind a port , listen and accept a socket and the client connect to the server and send it a message.

When I set up my sctp server in a remote server(eg. 192.168.0.200) , the client get a connection timeout from (connect() function. I looked in The server side code and the accept is going on OK with no error code return.

Where should I start looking and what could be the problem for this? Note, that I replaced IPPROTO_SCTP with IPPROTO_TCP just for the check and it working fine with tcp.

Thanks for advance, Eyal
