we have a customer connecting via a static IP address and they are sending packets from randomly changing ports. We have a listener service running on a PC.
Without the firewall it works fine, but when I set up a rule to forward traffic from the customer to a specific machine on our network I see the packets being dropped and a connection between the customer and the listener does not happen.
We are accepting traffic from 1:65535 to 3750
this is the log contents.

Do I need to open a rule for the reverse of this (IE all FROM the workatation TO the customer is allowed?)
