Hi
this might sound like a stupid question but I need to know if I can add a second intra array IP address range to an existing TMG array?
We have a physical array using 1.1.1.0 network for the intra array network and the 2 server intra array NICs are connected using a crossover cable.
We need to add 2 VM TMG servers to the array. We can unplug the crossovers and connect the NICs to a switch but we need to add the network to the ESX environment and then route this through the network core to get it from the box to the physical switch (so say the network lads).
The problem is that they checked the core config and the 1.1.1.0 network has already been routed in the core presumably for a similar issue with our Exchange environmant.
I really don't want to change the existing intra-array network range to something that we can route. I don't know fully what implecations this will have and we can't really have the downtime as this array reverse proxies our internal web and OWA resources.
I wondered if the simplest thing to do is just to add an additional network i.e. 3.1.1.0 to the intra array network properties and will TMG dynamically update the firewall rules and policy objects to reflect this change?
cheers
Mark
