NAT all traffic from alias except a single port/IP

Yes, the 192.168.1.62 machine is fine with routing directly through the WAN interface. Have to clear states to get it to behave that way though since it holds on to the OPT1TOPIA interface until states have been refreshed.
EDIT: I do also notice that it helps restarting the 192.168.1.62 machine when making those changes or else it stays in a funky state. Upon rebooting it behaves at it should through the WAN_DHCP interface.

I was able to figure this out! Attached are the rules. I figured out that it was traffic on port 563 that was needed and did a bi-directional rule.
Is there any easier way to do bi-directional rules than how i did it here?

The first rule with the source port 563 is probably doing nothing.
There is no such thing as a bi-directional rule on an interface tab. They only match traffic being received by that interface.
The firewall state is created which automatically allows return traffic for that connection.
