Affinity for internal ISA array with SNAT external fire... - 22.Oct.2007 7:17:24 PM

Hi,

Just checking if I understand this correctly. We are planning to deploy an ISA 2006 array with NLB on our internal network for ActiveSync publishing.

The array servers will be sitting behind external firewalls that use source translation,  all requests appear to come from the firewalls 'internal' interface, same address, different port. If I understand the documentation correctly this means that all traffic is likely to be directed to the same ISA server for all clients.

We have to use the SNAT on the external firewalls as they are not on the default route out of the network (outgoing traffic goes through different firewalls) and it is not possible to set up a route back from the ISA servers.

In the above scenario am I completely out of luck? Is there a way to configure the NLB to take the port addresses into account when maintaining sessions?

I'm assuming I will need to locate the array somewhere else on the network but would appreciate any suggestions.

Thanks in advance
Chris
