ICMP Blocked!
« on: October 12, 2017, 09:15:08 AM »

The Covr is blocking icmp request and there appears no way to allow them.  This necessary for my ipv6 setup.  Is there a hidden advanced network page like some of the other routers have?

Most router manufactures will filter/block IPv6 ICMP requests for "security reasons". ICMP should not be a requirement for IPv6.

Are you getting an IPv6 address in the router?

What modem do you have?

Are you having internet connection issues?

The Onhub has nothing to do with it, it's downstream from my router and only serves as an access points for my 6 Nest Cameras that wont stay connected to the Covr.  ICMP is a requirement for IPV6 tunnel when your lazy ISP does not provide a native one.  You must be pingable in order to set up a tunnel.

There is no Modem.  I have Fiber and my setup does not require that I use a Modem/Router from the ISP.  It is just Ethernet from my ONT (Optical Network Terminal).
