Draytek RDP


We have a Draytek 2820n i've been trying to enable RDP access to the server, i've setup the nat i'm confident that it's setup correctly well think i was anyway.

AP001192> srv nat showall
srv nat showall
Index   Proto   WAN IP:Port                 Private IP:Port             Act
R01     TCP     -- ALL --:3389               Y
R02     TCP                 Y
R03     TCP     -- ALL --:443                 Y
R04     TCP     -- ALL --:25                   Y
R05     TCP     -- ALL --:80                   Y
R06     TCP     -- ALL --:987                 Y
R07     TCP     -- ALL --:143                 Y
R08     TCP     -- ALL --:993                 Y
R09     TCP     -- ALL --:11636               Y

This is how it looks and i've tried everything to get 3389 allowing but it's not working. I'm not too familar with Drayteks and it's all sort of guess work for this one i'm afraid can anyone point me down the right track.

I've checked the server side and this appears to allow rdp access.

The RDP connection should be set to use ALL as the wan port in the same way as the rest are, whats your reasoning in putting in there? Also opening up 3389 on the wen is a massive safety concern, you should pick a random port and redirect that to 3389.

Remove R02

Does the SMTP rule work?
Is the RDP server using the Draytek router as it's default gateway?
Alex YoungAuthor Commented:
Yeah everything works even owa works
Craig BeckCommented:
So is the firewall on the router configured correctly?

Also, is the firewall on the RDP server allowing connections on port 3389 from address ranges which aren't on your LAN?
Craig BeckCommented:
Hmmm, I don't understand why that worked... you already had the rule configured correctly at R01...
