LAG's "Configuration Datastore" service never goes green in NAT enabled environment - SP refreshes always Pending

Environment

Novell Access Manager 3.1 Access Administration
Novell Access Manager 3.1 Linux Access Gateway
NAT enabled Access Manager setup

Situation

An Access Manager setup was performed where a Network Address Translator device was located between the Linux Access Gateway (LAG) and the Admin COnsole as follows:

AC/IDP-----Private Network------NAT------Public Network-----LAG

With this setup, the Admin Console's (AC) Health panel for the LAG always shows yellow for the service "Configuration Datastore" with a corresponding message "Some configuration datastore replicas are not responding". Despite this warning, the Administrator is able to push configuration changes to that LAG successfully.

However, the command status goes to Pending and stays there. Clicking the Pending link to get to the Command Status page shows that the Configuration command was successful but the "Service Provider Refresh" command is in Pending.

Resolution

Access Manager currently does NOT support a NAT device being placed between the Admin Console and any of the remote components such as LAG, Identity Server, SSLVPN or Java Agents.

In the setup above, the LAG ESP is still trying to talk to the private IP address of the Admin Console and not the public NAT mapped address.A snippet from the LAG's /var/opt/novell/tomcat5/logs/catalina.out is below. You can see that it's trying to do an ldap connection to the internal ip address of the AC (10.251.202.150) instead of it's public NAT addr (137.65.1.111).
