Linux as a router for SCTP and UDP packets
I am searching a lot for any inbuild utility in linux to aact as a router to route packets from An IP + port to another IP+PORT combination. In NAT i can get only IP based forwarding. But I need
packets coming from IP1 Port 1 to redirect to Ip5,port 5 and from IP1 port 2 to IP6 port6 combination.
I could find rinetd utility on more searching, but this is restricted only to TCP , however I need application for SCTP and UDP packets.
Pls help me in this
