    Hi,

    I have a weird issue with my Pfsense setup. It's an SG1100 and every time I visit Hungary after a while it stops working.
    First I experienced issues with my home devices (cameras are offline, I couldn't connect over Wireguard VPN, Tailscale is not working on devices, etc.)
    My girlfriend was nice enough to visit my apartment, restart my SG1100 and it worked for a while, but after a few hours stopped.
    Currently I can
    -connect over Wiregouard and ping Pfsense and a few devices that has static IPs (usually I use Pfsense DHCP reservations for static IPs, but maybe some devices are hardcoded like Synology, Proxmox)
    -I can connect to Proxmox GUI and access VMs

    I can't
    -ssh to Pfsense (even the VMs are in the same network) neither from VPN
    -open the Pfsense web gui

    I had one firewall rule that rerouted any outgoing 53/853 traffic back to 127.0.0.1 so devices have to use Pfsense as a DNS. But I turned off. Beside that I only have rules blocking IoT network to reaching out main network.

    Here is my network setup
    192.168.22.0/24 - main network
    192.168.88.0/24 - Wireguard
    192.168.33.0/24 - IoT network

    Last time I experienced issues when
    -used DynamicDNS updates to Cloudflare
    -or Pfblocker updates itself

    Did I misconfigured something with PfBlocker? Can someone please take a look on my logs.

    Thank you!
