Losing My Mind on a Business Trip

This might get ranty but I’m losing my mind here. I have a local wireguard VPN that I use to connect from my worksite to my home on my laptop and everything typically runs fine. I can access my resources and take advantage of my pihole.

The company sent me on a work trip in another country. I connect to wireguard and try to access my local resources and no luck. I can access my pfsense via its IP address/port but not by dns name. I thought ok well let me check my other resources via direct IP and I get nothing. Here are some further troubleshooting steps I’ve taken:

  • ping other servers on the same vlan via their IP: failed
  • ping other vlan gateways by IP: passed
  • restarted pc and pfsense and tried the servers on the same vlan again: failed
  • changed the wireguard config from AllowedIPs from 0.0.0.0 to add the subnets of the servers with a /24: failed
  • Checked firewall logs with nothing specifically being blocked that I can see.

I had an ovpn server Ive left running that I’ve used before switching to wireguard, and I’ve done the exact same troubleshooting steps.

I tested my wireguard config before leaving the house and I have a brand new laptop that I set up wireguard on and tested with no issue.

Any ideas on where to start looking would be great.

Is it possible you have some country blocking defined in your pfSense?

Does the local network you are connected to overlap with the networks you are using in pfsense?

I don’t have anything geoblocked, and I am able to log into pfsense.

That might be a possibility depending on how they have their network segmented. They are both 172 networks but a huge gap in between them. The wireguard is on a 10. network. I am routing all traffic through wireguard.

Not sure if that helped, but the TLDR is maybe with a huge astrick.
