      Hi All, we just replaced our firewall with PFSense and so far everything is running great except for one issue that i'm unable to resolve.

      We have LAN, WAN, OPT and multiple VLANS on the LAN interface (Each VLAN is assigned to separate customer with an RDP Server).

      We have a hosted exchange server on the LAN interface.

      pfsense web UI is enabled on port 443

      Customers can no longer access the Exchange server with outlook, also trying to access the https://exchangeserver.x/owa outlook web access the pfsense webconfigurator opens.

      All other https:// websites work fine, its just anything on the LAN interface that they have problems with

      Because of auto config rules in outlook they are attempting to access the external NAT IP of the exchange server on the LAN.

      Any help would be appreciated

        Make internal DNS return the internal IP address when asked to resolve from LAN.

        DO NOT set a source address/port in a port forward or firewall rule unless you KNOW you need it!
