Yes, it's all "Linux Bridge" bound to physical ports

I just remembered that OPNsense is running as a VM inside Proxmox.
Maybe that can cause the issue?

Thanks.
With the settings you described, ping works. -> MTU is 1500

Alright, I have an ISP-provided cable modem running in bridge mode.
The OPNsense box is connected to it via a network cable and uses DHCP to get its WAN IP.
Regarding MTU: I'm unfamiliar with that topic. How can I check this?

Just wrote to my ISP, they claim they don't block anything.
I double- and triple-checked the GIF config and I'm pretty sure its correct.
What else could there be?

Gateway monitoring shows OFFLINE with 100% loss.
I started a packet capture while pinging 2606:4700:4700::1111.
For the TUNNELBROKER interface I can see ping packets going out from my local to the remote tunnel address.
For the WAN address I only see one outgoing packet to the TunnelBroker Server IPv4 Address (red).
(see attached screenshots)

No, I have a static IPv4. Also I checked that my IP matches the one configured in TunnelBroker.

Hi there,
I have an issue connecting through a TunnelBroker 6to4 tunnel.
Packets are going out, but nothing comes back - I can see the outgoing packets in the firewall live logs. Also I'm not behind a CGN.
My client is getting a valid IPv6 address from the router and pinging the router itself works.
Configuration images are here: https://imgur.com/a/GSPXYI6
Values from TunnelBroker:
Server IPv4 Address: red
Server IPv6 Address: green
Client IPv6 Address: blue
Routed /48: yellow
Any ideas on what could be the issue / what to test?
