hey, we have zimbra hosted with an outside provider. I currently have AD auth on port 636 with SSL, but its just a cisco router nat'd straight to host vlan(no firewall). Now with a NEW DC, Iím trying to setup AD auth on port 636 with SSL through our PaloAlto Firewalls, but with no luck. I can get the 3268 but thatís not SSL. I didnít set this up in the beginning, I walked into this configuration. Do you know if I have to change a config on the DC to get this to work? I check the ports 636 and 3269 inside my network(no firewall) and it show open.
