We are about to install a IPSec tunnel between HQ and a branch office. We have two ISA Servers 2006 with NLB at HQ, but want to install a Cisco at the branch office. We have contacted a Cisco reseller and they don't recommend that we use our ISA server for VPN, and recommend that we set up a Cisco ASA 5505 at HQ and Cisco 881W in the branch office.
Is there any known problem with combining ISA and Cisco VPN?

I don't mess with any arrays myself, but I'm sure there were some issues there with NLB -vs- VPNs. If a Site-to-Site it may reinitialize and connect to the other server but it probably uses the actual IP# and not the VIP.
If it is an incoming Remote Access VPN then I really don't know. I think there might be an article on the site here somewhere about it,..I'm sure I read something along those lines. But I can't remember any real details. I know that this whole subject has been one of the more obscure things about the product to try to understand.
