Can't Ping via WARP
I'm not able to ping within the private network when connected via WARP.
SSH, HTTP, etc. works fine. How can I allow icmp?

CZero Trust needs more docs about this, but there's two things I would check:
- Under Settings -> Network -> Firewall if ICMP is enabled under Proxy
- Check your tunnel logs to see if it's enabled or not. You need Http3/quic (can't be forcing http2) and check if it's disabled in logs on startup. Should see something like
Aug 09 00:15:47 .... cloudflared[2606146]: 2024-08-09T00:15:47Z WRN The user running cloudflared process has a GID (group ID) that is not within ping_group_range. You might need to add that user to a group within that range, or instead update the range to encompass a group the user is already in by modifying /proc/sys/net/ipv4/ping_group_range. Otherwise cloudflared will not be able to ping this network error="Group ID 0 is not between ping group 1 to 0"
If it is disabled, with instructions on how to fix
Aug 09 00:15:47 .... cloudflared[2606146]: 2024-08-09T00:15:47Z WRN ICMP proxy feature is disabled error="cannot create ICMPv4 proxy: Group ID 0 is not between ping group 1 to 0 nor ICMPv6 proxy: socket: permission denied"
