Hey guys, I just had to share my joy. Multiple ISA firewalls running on Win2003 using NLB. PPTP and L2TP/IPSec -- SWEET and it works with WinXP SP1 and allow the other VPN clients that had a problem with the reponses coming from the "wrong" IP address. Next step is to check it out in VPN gateway to gateway mode. Two VPN gateways at the local site, two VPN gateways at the remote site. See if fail over works smoothly. One downside -- I still have to create the arrays the old way, the NLB Manager is a bit "flakey" for want of a better term and leads to more stress and strain then required. Create the NLB arrays the old fashioned way, no problem, and everything works. :-) I'd be happy to hear from anyone who's had a good experience with the Win2003 NLB Manager 'cause its always good to hear from the other side, and maybe I can learn a thing or two!
