You need to specify the direction of the rule (in). Also, since your PC is in the WAN subnet, you should disable reply-to.Not sure how you were able to create a WAN rule without specifying the direction. Or is this a floating rule?
That's odd, the error message clearly shows a rule without direction ("pass quick") and with reply-to set to your home router ("reply-to (vtnet0 192.168.3.1)"). Is this your only rule? You might want to check Firewall: Diagnostics: Statistics: rules for duplicates. Or delete and recreate the rule.
