[isapros] FW: TMG Unsupported

Hey Jim,

The "not so nice":

HTTPS Inspection limitations

Issue: There are a number of limitations you should be aware of when enabling 
the HTTPS Inspection feature on Forefront TMG.
Cause: The following features are not supported:

 *   Extended Validation (EV) SSL certificates.
EV certs are getting quite popular now, so I see the exclusion list having to 
grow quite quickly and an unpleasant admin overhead :(


Forefront TMG does not support IPv6 traffic
Issue: IPv6 traffic is not supported by Forefront TMG (except for DirectAccess).
Cause: Filtering of IPv6 traffic is not supported, and all IPv6 traffic is 
blocked by default.
Solution: It is recommended that you disable IPv6 traffic on the Forefront TMG 
computer or array members. To disable the IPv6 stack on the Forefront TMG 
computer or array member, see Knowledge Base article 
KB929852<http://go.microsoft.com/fwlink/?LinkId=179983> 
(http://go.microsoft.com/fwlink/?LinkId=179983).
This is a real shame as a lot of "hardware vendors" now provide this out of the 
box; this could make it hard to introduce TMG as a 'proper firewall' if 
customers are seriously looking at deploying IPv6 :(

Can you expand on the "except for DirectAccess"? E.g. could TMG be a dedicated 
edge firewall in front of UAG running DA? Or is it only when DA is installed on 
the TMG host itself?

A lot of other statements fall into "same as ISA" or "glad to see them listed" 
:)

One that I think should be included (that isn't) is a statement about the lack 
of support for stateful session failover when using NLB/HLB, as I believe TMG 
EE still cannot do this. A lot of people seem to assume it does, especially 
when comparing to 'da competition'.

Cheers

JJ

We just published the "unsupported stuff" for TMG on TechNet.
