Not sure if I should throw this in the TMG forum or here. We have an Exchange 2010 environment and TMG firewall. My problem is with autodiscover. We have a SAN cert for mail.domain.com and autodiscover.domain.com. Can I have our ISP point our public IP address that we use for mail.domain.com to autodiscover.domain.com too? Basically mail. and autodiscover. would share the same public WAN IP address? Currently I have autodiscover pointing to another of our public IP's and I would like to consolidate these addresses.

The hostnames for mail and autodiscover may use the same IP address.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."
