Port forward to SBS 2008 for RDP

when you try and remote in are you using mstsc /v:server:port
? and specifying 3388?

correct

1 - try normal 3389 and confirm working.
2 - try another port perhaps 3380 - often the ports work in pairs and 3388 will be using 3389 also.
3 - what router are you using?

just changed external to 3387 to test didn't work either

i can;t change the port forward 3389 people are using it to get to the TS box.  Plus i'm not on site so if it doesn't work i'll loose connection.

It's a TP-Link

changed to 3380 no go.  

I can access the server via 3389 in the network fine.


also all other PF are working,  ie 25, 80, 443, 1723, 987

just change the port on the sbs to 3388 and port forward the router 3388 to the sbs.

run regedit

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp
change portnumber to 3388 (decimal)

when you have to RDP use IPADDRESS:3388

Thanks Thethical  i really would like to not have to change that.  The port forward should work.

only thing i can think of is the sbs 2008 firewall is blocking it somehow   but i cant find anything on it to indicate it is.

What is your external router? And how have you setup the port forward?

TP-Link TD-8840

Server Name        External Port Start        External Port End        Protocol        Internal Port Start        Internal Port End        Server IP Address        Remove
Mail (SMTP)       25       25       TCP       25       25       172.16.4.250       
Web Server (HTTP)       80       80       TCP       80       80       172.16.4.250       
PPTP       1723       1723       TCP       1723       1723       172.16.4.250       
TS RemoteServer       3389       3389       TCP       3389       3389       172.16.4.10       
Secure Web Server (HTTPS)       443       443       TCP       443       443       172.16.4.250       
server       987       987       TCP       987       987       172.16.4.250       
server       3380       3380       TCP/UDP       3389       3389       172.16.4.250       

i can't be a router issue all the other port forwards are working no problems

i have tested creating a new one 2500 to 25 worked.

tested 3387 to the windows 2008 box worked.

Sorry, I'm not overly familiar with SBS 2008, but does it have a similar "Windows Firewall with Advanced Security" applet to 2008?

If so, you may have to check the Edge Traversal settings on the "Remote Desktop (TCP-in)" Inbound Rules.

the Edge Traversal settings was off.  I turned it on still no go

If your using SBS 2008, and the 2008 TS is on the network, why not just goto RWW, login, and access it from there? Providing your the admin of the SBS, you can give yourself and the other users access direclty from RWW.

If this is not the way your wanting to access the server, then change the RDP listening port of the 2008 TS from 3389 to 3390 or something like that as another user posted. Open up that port on your firewall and make sure it is forwarded to the 2008 server. You then access the TS2008 from RDP in EXTERNALIP:3390 Also, make sure you have opened up this port in the SBS 08 and the TS 2008 firewall if it is on, by default it is turned on in the SBS 2008 GPO.

Remote web Workplace is a good option but if you want direct access using RDP, SBS 2008 has a new feature called TS gateway. With this you can use the remote desktop client (RDP) to connect directly to any computer on your network to which you have permissions, using the standard RDP client. You do not need to do any port forwarding so long as you have set up the default 443 and 987 SBS ports, and the RDP client will automatically connect using port 443 which is more secure as it uses SSL. The only difference is you have to add the name of the TS gateway computer (the SBS) in the RDP client. Then just enter the TS name or computer name to which you want to connect the same as you would on a LAN with the RDP client. See the following link. The TS gateway notes are contained in the description of the last 3 images:

maybe a non-issue but thought I'd ask.... do you have a dsl/cable modem in front of your router that may need the additional port opened and forwarded to your router?
