We have configured a RD Gateway server (with Web Access on same machine) with two network cards. The server is working fine, however the "connect" of an application is taking a long time. Upon investigation via Wireshark it turns out that the RD Gateway server is trying to connect to the Active Directory server via the wrong network interface card on port 389.
A static route has been setup to force the connection to the AD server via a specific NIC, but apparently there is something in the Remote desktop services that forces it to use the wrong network interface (0; with default gateway on it).
The connection is working fine if I try ping, and telnet (on port 389). Also I later on see successful communication in the Wireshark trace using the correct network interface (using same port). That is however only after 1 minute, so this seems to explain the login delay.
I expect the communication to start from the RD Gateway, is there an NIC directly bound to it, and how to change that?
Edit with some details:
- The internal network is on interface 192.39.212.112
- The external network (clients) are on interface 192.39.58.112
- The AD server is at 192.39.212.227
