I didn't reboot the HG612 no but the ping responses started working straight after I disabled it.
How about re-enabling its firewall and setting it to respond to pings? Just see what happens
The worst is that it doesn't work.
Edit: Uh! It would need an external IP address on your Lan. Forget that idea
