i´ve got a problem. I have installed a pfSense on a esxi as a virtual machine. Internet connection, vpn and port forwarding works fine.
I get the following message in the event log:

The source ip is my domain controller (192.168.200.2) and the destination is a client pc on a different subnet (192.168.1.53). These logs are produced by connecting this client to a exchange account. (exchange 2007, hosted by the domain controller). Routing working fine between these subnets, i can ping the DC, working over RDP on the DC and i can open network drives over smb from the client for example. Only connecting to exchange do not work.

I´ve got the following ACLs on Firewall Rules configured:

But that doesn´t work. With creating a easy rule over the system log (see in first picture) it doesn´t work too.

I also checked personal firewalls, that can not be the issue.

Have you guys any idea ?

thanks a lot

cheers
