Hello, I have the following config: Internet | x.x.x.131 x.x.x.130 x.x.x.129 | Cisco IAD provided by CBeyond doing NAT and forwarding x.130 ports 25, 80, 443 to 192.168.9.2 | 192.168.9.1 | DMZ (192.168.9.x) | 192.168.9.2 | ISA 2000 (running on SBS 2000) | 192.168.1.99 | LAN (192.168.1.x) I have split DNS in place so that mail.domain.com resolves to the internal addy of 192.168.1.99 internally, and x.x.x.130 outside. I have purchased an SSL certificate for mail.domain.com and have it installed on the SBS server. Internally, I can access OWA using SSL without a problem using the FQDN/Exchange or NetbBios/Exchange (I do get the popup about the name not matching when using the NetBios name as expected). However, externally it just hangs at a white screen, almost forever <G>, and then fails with "Cannot find server or DNS Error". If I turn off SSL, I can access OWA from the outside. I've looked everwhere, re-run the wizards, etc to no avail. I can TelNet to port x.x.x.130:443. I'm thinking the NATed NAT has something to do with the SSL. Have any ideas? This six hour upgrade is now in the days <G>. Chris
