RDP External

HI Please can you assist me, I'm trying to connect to multiple machines behind a firewall. I have done this for the first machine but I'm not able to on the 2nd or 3rd machine I want to access.

MY IP:3389 > Machine 1 > Successful

My IP:3390 > Machine 2 > Unsuccessful >  I have opened a port on the router for 3390 which points to the local ip.

I can connect to all the machines internally but externally on machine 1!

the port 3389 is for the RDP thats what it's connected..

2nd and 3rd machine can connect as same as first machine

use   2nd machine ip:3389  and 3rd machine ip:3389

all the best...

If I do this externally I always end up remoting on to machine one! I only have 1 static IP

remote.domain.ae:3389 > Machine 1 > > Secsessful
remote.domain.ae:3390 > Machine 2 >   > Unsecsessful

Internal Im fine

even though the rdp port is 3389 which is used for Remote desktop...

if you want to change the default RDP port on the server then youe have to change it from registry..

the default RDP port is always 3389

try again  
remote.domain.ae:3389 > Machine 1 > > Secsessful
remote.domain.ae:3389> Machine 2 >   >  now check and update..

all the best

Done still not able to connect

now i got it...

u have only one public ip.... u want to acess multiple servers over RDP

so you have to do natting from the firewall..

by natting you can publish multiple servers ..  

in natting 1 public ip will resolve multiple servers without any issue..

what is your firewall so i can guide you accordingly...

all the best..

Thank you - I've just check if port 3390 is open but I don't seem to be able to configure it so is is. I have added an rebooted the router. Its shown in the table but it not allowing!

The router is ASUS RT-AC68U

if you are trying to access another machine with RDP port 3390  then make it sure that machine port must be 3390
check the following image..

and that machine ip published on the router with the same port to forward the fraffic..

RDP port change
check and update...
