Wondering how to get your UniFi Router to respond to internet WAN pings?
How to allow ICMP ping on UniFi WAN interface?
This works by adjusting the firewall rules on your administrator interface for most Ubiquiti UniFi gateways/routers:
UXG-Enterprise
UXG-Lite
UXG-Max
UXG-Pro
UDM-Pro-Max
UDP-Pro
UDP-SE
UCG-Max
UCG-Ultra
UDW
In your admin interface go to:
Settings COG >> Security >> Traffic & Firewall Rules >> Advanced (top right select)
You can optionally select the ‘Internet In’ interface.
Now click ‘Create Entry’ and select type ‘Internet Local’ (I know it sounds incorrect but this is correct)
Under name type ‘ICMP Allow Ping WAN’ or whatever you like.
Action ‘Accept’
Protocol ‘ICMP’ and tick ‘Before Predefined’ (note the ICMP is a scrollable list to find it further down)
Now select ‘Echo Reply’ in the IPv4 ICMP Type Name.
Do NOT tick Match Opposite.
Leave the Source and Destinations as default which is ANY.
Add finally click ‘Add Rule’ at the bottom.
Now test remotely and it should work.
If it doesn’t work then you may have an upstream router (maybe ISP supplied) that is blocking. Make sure its in bridge or full DMZ to the UniFi router.
And if that doesn’t work check your NAT is setup correctly.
