Please Help!

I just cannot establish RDP connection from one of my internal networks to external Terminal server.
I got several subnetworks (10.10.10.0,10.10.20.0,10.10.30.0 etc.) and several public IPs (82.10.10.1-82.10.10.16). All users are using NAT on external IP 82.10.10.2, but network 10.10.30.0 users are using NAT on external IP 82.10.10.15. Users from network 10.10.30.0 are experiencing a problem conncting to remote RDP server. All ACL on my PIX 515 are correct.
Where might be the problem?

My first thought is whether or not the TS's IP address has port 3389 allowed on it.

Is the External TS located at another location? Is it behind another firewall?

Hi.
Thanrs for reply.

No, Terminal server works properly. I can connect to this server from any subnet exept 10.10.30.0.
I think, the problem is connected with NAT.

Here is a sample of my config:

global (if_ISP) 1 interface
global (if_ISP) 2 82.10.10.14
nat (inside) 1 10.10.10.0 255.255.255.0
nat (inside) 1 10.10.20.0 255.255.255.0
nat (inside) 2 10.10.30.0 255.255.255.0
