Your suggestion was actually the first thing I tried :) Unfortunately, each host listens on a specific IP address for that virtual host. So if: webmail.example.com = 10.0.0.10 subversion.example.com = 10.0.0.11 timesheets.example.com = 10.0.0.12 and pf sends a request for webmail.example.com to timesheets.example.com, the request fails. -- Regards, Doug
