NLB Site-to-Site VPN - 17.Jul.2006 2:04:46 PM

I'm expreiencing a strange problem.

We've got a site where we would like to implement ISA ent with NLB. the other site is running ISA 2004 std. The ISA ent config is as follows:

network for intra array comms
Network for external
Network for Internal

The External network and internal network is NLB with the virtual ip.

The internal clients are using the virtual ip for their gateway. and the ISA std uses the external virtual ip for the site-to-site vpn.

Everythings connects and the site-to-site vpn is up and running.

We exprieenced the following:

1. we could only ping the other network from the site-to-site vpn owner. all other clients could'nt we also didn't see any thing in the log files wierd.
2. We decided to installs the whole envoriment on virtual pc 2004 sp1 and got connection failed in the logs files.
3. after playing a bit it suddenly started working. deciced to check if the NLB worked did a shutdown on the site-to-site vpn server and saw the second server taking over the vpn. Still worked started the first server again and shutdown the second server it stop working and can't get it working again .

Please any advice. I can seems to find good documentation for this.

Don't worry sorted this myself out. For some reason did the one IT guy decided to enable trend firewall client and that broke the config with funny problems.
