ports for openvpn and websockets : <p>this will sound a silly question....
but id like to know the following.
i was going to install a freeswitch voip server on small intel nuc and on another intel nuc (nucs are small low powered desktop like units ) i planned to install openvpn to be used as a very useful vpn for when im on a dodgy wifi connection.</p>

<p>since id like openvpn to be running on port 443 tcp and since freeswitch ideally runs on 443 tcp i figured id need two seperate computers - hence the two machines on 2 completely different remote internet connections .</p>

<p>however im rather inclined to install both openvpn port 443 tcp ( running all the time) and also freeswitch websocket server ( listening on 443 tcp) running on the same computer and behind one router on a friends broadband connection port forwarding anything coming in for 443 tcp to the same local ip add of the same server running both freeswitch websocket and openvpn - is this a good idea?</p>

<p>id sooner not change the listening port on openvpn - since the default 1194 may well be blocked from hotel wifi etc and web sockets will undoubtedly respond more reliably if its listening on 443 tcp.</p>

<p>can two services listening on the same  port / protocol work ok (nat wise )behind the router ?</p>
