Redirect incoming traffic to an other port (ubuntu openvpn server)
My problem is a bit complicated, but i have simplified it...
I have set up an openvpn server on ubuntu via port tcp 443.
The server use a public network and almost every ports are blocked (not 443)
So when a client connect to the server, if it send traffic needing a blocked port, the connection cannot been etablished of course.
So i d like to know if it is possible to redirect all incoming traffic on the server to an other unblocked port (like 443) to bypass firewall.
I dont think openvpn offer this possibility but maybe with linux it is possible...
