OPM Add DataSource Problem

[tlkendall]

I have 6 clusters in my environment and have been able to add 4 of them into my OPM 1.1.0RC1 server and they are working perfectly.

The 2 that will not add are reporting a "Network Access Failure - Failed to connect to cluster" in OPM.

The 2 that are failing are production clusters with all lifs online, pingable and accessible.  I've been digging through knowledgbase articles and syslogs and can't seem to find the problem.

event log show on the 2 failing clusters is not reporting any events.

Any advice is appreciated.

Found my problem.  Turned out to be MTU settings, or rather a problem with passing Jumbo Frames across the WAN to these particular clusters.
