Awaiting update from their support staff ... it could be their apps modify the packets in some way in order to get a reply?
My tcpdump looks like this:
Code:
22:08:27.393090 IP 10.0.69.214 > dns.google: ICMP echo request, id 1458, seq 1, length 64
22:08:27.402279 IP 209.85.174.232 > 10.0.69.214: ICMP time exceeded in-transit, length 76
22:08:28.537525 IP 10.0.69.214 > dns.google: ICMP echo request, id 1510, seq 1, length 64
22:08:28.551100 IP 209.85.253.253 > 10.0.69.214: ICMP time exceeded in-transit, length 76
22:08:29.685557 IP 10.0.69.214 > dns.google: ICMP echo request, id 1561, seq 1, length 64
22:08:29.698914 IP 108.170.233.41 > 10.0.69.214: ICMP time exceeded in-transit, length 76
So a ping to target (dns.google) followed by a time exceeded reply from a different ip. This time exceeded packets gives traceroute info about which hosts the packet are passing.

Despite every hop timing out I see this in tcpdump

Despite every hop timing out I see this in tcpdump
So the packets are received by your router, probably not proton then.
Could you see the same time exceeded packets sent to your lan?
Code:
tcpdump -i br0 icmp
But beware, this Interface is much noisier so you might to dig through some to find your packets.

Only noise seems to be .5 and .6 the Sky boxes sending keep alive pings I guess.

Only noise seems to be .5 and .6 the Sky boxes sending keep alive pings I guess.
The only time exceeded packets here are from the router itself, no others. This is where we differ:
Code:

22:25:48.184738 IP 209.85.174.232 > 192.168.128.221: ICMP time exceeded in-transit, length 76
22:25:50.020521 IP 192.168.128.221 > dns.google: ICMP echo request, id 2591, seq 1, length 64
22:25:50.032990 IP 209.85.253.253 > 192.168.128.221: ICMP time exceeded in-transit, length 76
22:25:51.252702 IP 192.168.128.221 > dns.google: ICMP echo request, id 2592, seq 1, length 64
22:25:51.265604 IP 108.170.233.41 > 192.168.128.221: ICMP time exceeded in-transit, length 76

In your case the router seems to block these, or at least it's not forwarding them.

That's not something I would have set/even know how to set ...

No... and it's not blocked by the firewall, atleast not in the forward chain which is used for access control... we even tried to explicitly accept icmp type 11 and it still didn't work...
And it's weird that it works for me but we have different routers so obviously something is different in fw implementation.

Works for you as in: you have ProtonVPN and use their WireGuard config file in your router?

No, as your router receives the "time exceeded" messages from all hosts on wgc1 this is not a proton vpn problem. But we both get these on wgc1 but my router forwards them to br0 but your router don't.
The router doesn't care about which vpn supplier we use, it behaves the same. But something is different between yours and mine.
 
Nothing but headaches with this fw implementation. Im not sure it's for me, got a OpenWRT router on the shopping list to be honest.
