CONFIGURATION FOR VPN BETWEEN 2 SERVERS PIX TO PIX


2K NT 4.0
SERVER1-----PIX1----HUB/ROUTER-----PIX2-----SERVER2
10.1.X 10.2.X

I have verified that I am able to create a domain trust when bypassing both the PIX'x. When the PIX's are hooked back up, can see packets crossing but no trust allowed.


I have set up an IPSEC tunnel between two PIX 515's. I am able to Ping both the IP's of the Servers behind each of the PIX's, but I am not able to create a trust between them. I have also tried doing a trust between two NT 4 machines but the same results (domain cannot be contacted). I can tell from the PIX that the tunnel has been created and have verified that packets are crossing the VPN. If I set up IIS on one of the servers, I am able to reach server1's web page through the 2 PIX's from server2. I believe the PIX may be filtering my packet information which is needed for the trust but I'm not sure. Listed below is one of the PIX settings:

What am I missing? NetBios & WINS have been installed and I also tried using LMHosts.
 
HI.

> NetBios & WINS have been installed and I also tried using LMHosts ...
It still seems like a name resolution issue.
How exactly did you try?

Try with LMHOSTS on both servers, using #PRE + #DOM paramters (and rebooting the server afterwards).

Try with WINS configured and verified to be working.
I suggest WINS on each server with proper replication between them.

Make sure that each server can ping the other domain using computer name AND using domain name.

Verify that trust relationship over VPN is actualy what you're looking for. Maybe other solutions like TS on each side can work better for you, depending on your organization needs and plans.

Thanks, for the information. It had to do with an installation of NT 4 server. After re-install plus service packs update for NT 4, I was able to trust using LMHOSTS.
