I'd like to monitor my router connectivity so I get alerted if the home internet connection goes down/offline for some reason. Have an ER605, 2 switches and 3 EAPs. All fully adopted and maanged by a locally installed OC200.

Ideally would like to use something like UptimeRobot

I want to only enable certain public IP addresses to Ping my WAN IP and get a response, anything else should get get dropped (as though pings are ignored).

However, even when I disable the "block Ping from WAN" and add a couple of Gateway ACL entries to only permit certain hosts for UptimeRobot for ICMP and then a following rule to Deny all others, I seem to receive Pings from other addresses as well (testing via the Central Ops website)



Any suggestions from anybody who has got this to work?

So we're clear, I want to achieve:

1. A perfect stealth report from the ShieldsUP test at www.grc.com
2. Allow PINGS to come from specified IP addresses only.

Has anybody been able to make this work running their ER605 under an Omada controller (rather than amending firewall settings on an unadopted unit via it's local web GUI)?
