    Hi, I need to know if it is possible to have forefront TMG redirect outbound web traffic to a an alternate IP for a specific host name. Our client sent us software to test with a hostname, but wants it to hit their test servers at a different IP address. They thought just editing the host file would work, but forefront is still doing a DNS query when we run the software.

    I saw the ISA toolkit from Redline, and it appears to add advanced routing which would do exactly what we need, but it doesn't run on 2008R2/TMG 2010. Is there any other way to set this up? Or any software comparable to the ISA toolkit that is compatible with TMG? Thanks.

    Hi,

    You could try to edit the host file on TMG server. As TMG server has DNS cache, you should run ipconfig /flushdns, and restart firewall service to make it take effect.

    Regards,

    James

    If you still can't solve the problem with the 'hosts' file, then you could write an IsaScript script that used the OnRouting callback to rewrite pszHost to a different IP address.

    Sorry for the delayed response. Editing the host file on both members of the standalone array did indeed work as stated. When I made the change, we had not queried the DNS server recently, so no firewall restart was neccessary. Thanks for the help JamesYi.
