I upgraded from 22.1 to 22.7 and after firewall was back, it showed the red dot on top right with 2 errors:

2022-08-19T11:39:09 Error firewall There were error(s) loading the rules: no IP address found for puppet
2022-08-19T11:39:09 Error firewall /usr/local/etc/rc.bootup: The command '/sbin/pfctl -f /tmp/rules.debug.old' returned exit code '1', the output was 'pfctl: /tmp/rules.debug.old: No such file or directory pfctl: cannot open the main config file!: No such file or directory pfctl: Syntax error in config file: pf rules not loaded'

However I have the puppet alias with an IP there just fine:

puppet Host(s) 192.168.x.x 1

My firewall is working perfectly per tests I performed. Any idea on how to fix this or troubleshoot further?

Hello everybody,

Following advise on https://github.com/opnsense/core/issues/4389 I'm creating this thread here. I still think it's a bug on opnsense and/or wireguard implementation, but anyway, here it is.

I'm unable to make port forward working on opnsense. I tried without wireguard-kmod before and saw people saying that it should work with it, so I went ahead installed and rebooted, but still nothing. Both with kmod and without the behaviour is exactly the same. If I just change the VPN_XX to use OpenVPN tunnel, it works fine.

My setup is as follow.
- WAN = WAN / ix1_vlan34
- WireGuard tunnel = VPN_XX / wg1
- LAN = LAN_VPN_XX / ix0_vlan24
- Server running on LAN = 192.168.24.51

I have a port forwarding NAT like this:
- VPN_XX   TCP/UDP   *   *   *   10000   192.168.24.51     10000

Firewall rule on LAN_VPN_XX with VPN_XX gateway:
IPv4 *   LAN_VPN_XX net   *   *   *   VPN_XX   *

Wireguard VPN is configured and it works fine, I can curl and everything. Just port forwarding doesn't work.

Any idea?
