Title: no answer from peer at he.net
Post by: rsokoll on June 08, 2025, 02:23:35 AM
Hi,

I use an Ubiquity ER-X and to my best knowledge, everything is configured properly. Tunnel end is 216.66.80.30 which is tserv1.fra1.he.net.
The tunnel interface is up. But I cannot see (tcpdump) any answers to icmp6 ping requests to anywhere. When I tcpdump on the IPv4 interface for traffic from/to 216.66.80.30, I only see outgoing packets. My router's IP is set correctly in the web interface at tunnelbroker.net.

Any ideas?

I have the same issue, using the same endpoint, but from an OPNsense. All lights are green and I can see that I send traffic to the tunnel, but I never get a reply.
I opened a thread on the OPNsense forums today and asking for help how to debug this, just to make sure it is not a configuration mistake on my side. But reading your post, using the same endpoint, maybe we did it correctly (or the same mistake ;-))?
