Support for NLB on VLAN Tagged or Teamed Network Adapters

One of the most common questions we get is about TMG’s support for NIC Teaming and VLAN tagging with NLB enabled.

We have recently released Software Update 2 for Forefront Threat Management Gateway (TMG) 2010 Service Pack 1. This is a regular rollup of hotfixes which is available through Microsoft Customer Service and Support.

One of the issues fixed in this update is TMG’s support for NLB on VLAN Tagged or Teamed network adapters (See KB article 2449122).

With this update installed, Teamed and VLAN tagged NICs become supported scenarios (see NLB’s support statement for VLAN Tagging and teaming adapters for details)

This fix will also be included in future service packs released for TMG.

    would be nice to see general support of teaming within the os itself or does this trump MS's general support policy on teaming of nics?  Or does this apply to non TMG stuff?


  2. There seems to be a problem in this update with site to site connections. We have 3 sites connected via a PPTP site to site connection. After installing the update in 1 site we noticed people in that site could not access internal http websites across sites. They got proxy timeout errors. Uninstalling this update resolved the problem.

  3. Further to my previous remark: we tried installing the update in all sites and after that it seems to work fine.

    What if you want to use VLANs AND Teams together – is that supported?
