Error Code

I recieved this error in PfSense

There were error(s) loading the rules: /tmp/rules.debug:161: rule expands to no valid combination - The line in question reads [161]: pass in quick on $WAN reply-to ( em0 fe80::201:5cff:fe62:5846 ) inet6 proto { tcp udp } from any to 192.168.1.105 port 25565 tracker 1466974036 keep state label "USER_RULE: NAT " @ 2016-06-26 15:06:14

Somehow  that rule is very confused. It has an IPv6 gateway but is passing to an IPv4 address.

Looks like it's an automatic NAT rule though. I'd check the settings on the WAN interface (gateways selected), plus look at the NAT rule in question and its associated firewall rule.
