Hello

I have a port forward to a mail server inside a network.
the works fine when I am outside (on the wan interface) but from inside it will not work.

Can someone give me details on how to port forward to a webserver or mail server that will work inside or outside the network to a public IP?

so if I type the public IP inside or outside the internal network it will redirect back to the internal server.

Thanks

It seems you need to masquerade such traffic: http://wiki.mikrotik.com/wiki/Hairpin_NAT

typically - you don't do that. But if you really must do it then I suppose you should be able to do a src-nat translation on incomming packets for your inside network port from public IP -> internal IP.

kirshteins, thank you.
That was exactly what I am looking for already 2 days
