Solved: Re: RDP over VPN - Page 2

peteb41976 · ‎02-01-2007

I've been trying for a couple of weeks to establish remote desktop over a vpn with no success. I am able to establish a connection to the vpn but once connected, I am unable to connect by remote desktop.

You are trying to rdp from vpn client to inside client correct?

Your vpn client will get 192.168.2.x address. Client on inside you are rdp to will still be 10.x.x.x.

peteb41976 · ‎02-02-2007

When I established the connection I received 192.168.2.125 as my ip. Once connected, I tried to establish a remote connection to 10.1.1.2 with no luck.

The ip I'm trying to connect to is 10.1.1.2 subnet of 255.255.255.0, gateway of 10.1.1.1, public dns servers

I also noticed that I am receiving no default gateway with the vpn connection. Could this be the problem?

I am able to connect to \\10.1.1.2 and access files.

acomiskey · ‎02-02-2007

Not getting a default gateway on vpn is normal.

peteb41976 · ‎02-02-2007

Any idea why I can access \\10.1.1.2 but not establish rdp to the same address?

acomiskey · ‎02-02-2007

So the vpn works?

Windows firewall maybe? Can you rdp to 10.1.1.2 from the inside?

peteb41976 · ‎02-02-2007

It is working. Thanks for all of your assistance. I've checked on both the client and the server and both are set to allow rdp

peteb41976 · ‎02-02-2007

The vpn and access to \\10.1.1.2 are working. RDP to 10.1.1.2 still isn't.

acomiskey · ‎02-02-2007

Can you rdp when you are on the inside, not on the vpn?

peteb41976 · ‎02-05-2007

Nope.

acomiskey · ‎02-05-2007

So the rdp connection not working has nothing to do with the vpn.

Make sure rdp is enabled on server and that no firwall between you and server is blocking tcp 3389.

peteb41976 · ‎02-05-2007

I tried with the firewall set to allow rdp and then with no firewall with no luck. Are there any settings on the PIX I would need to enable?

acomiskey · ‎02-05-2007

If you are on inside coming from 10.1.1.x and attempting to hit 10.1.1.2, the traffic would not be hitting the firwall.

peteb41976 · ‎02-08-2007

Okay - When I am at work I can launch the vpn client, receive a 192.168.2.x address, and connect to \\10.1.1.2

When I am at home, I can launch the vpn, receive a 192.168.2.x address and I am unable to connect to \\10.1.1.2 I even changed all of my internal router settings at home to match those at work. (both hand out 192.168.1.x addresses) I am completely stumped. If I couldn't connect to the vpn at home I would think there was a setting which needed to be changed. But, everything is the same.

acomiskey · ‎02-08-2007

What kind of device are you going through at home?
