Hi,
i created an environment with an IPCop Firewall. My goal is to establish a RDP connection to Terminal Server (IP 192.168.70.12) on the good (GREEN) side of the firewall from a client on the bad (RED) side of the firewall. To make this possible i create
a port forwarding rule in the firewall, which forwards from port 7012 to port 3389.
![]()
Now i try to build up a connection from my client to the Terminal Server with mstsc and the address 10.0.14.118:7012 (10.0.14.118 is the RED IP Address of the firewall). When i try this, i get the following message:
"Login failure: user account restriction. Possible reasons are blank passwords not allowed, logon hour restrictions, or a policy restriction has been enforced".
In the EventLog of the Terminal Server i get the following Event:
An account failed to log on.
Subject:

Account Name: -
Account Domain: -
Logon ID: 0x0
Logon Type: 3
Account For Which Logon Failed:

What goes wrong here, what can i do to solve this issue? The RDP session works perfectly, when i open the connection from a client within the GREEN network and the same credentials.
Thanks in advance
Regards
Dave
