My Turris Omnia does not reply to ping request sent from the Internet to its eth1 IPv4 public address. It works fine with IPv6.
In LuCI, I checked Network -> Firewall -> Traffic rules and there is a rule “Allow-Ping
IPv4-icmp with type echo-request
From any host in wan
To any router IP on this device
In Status -> Firewall, the rule sees zero traffic:
Chain zone_wan_input (References: 1)
Pkts. Traffic Target Prot. In Out Source Destination Options
0 0.00 B accept icmp * * 0.0.0.0/0 0.0.0.0/0 icmptype 8 /* Allow-Ping */
How to enable ping?
