Ever since switching to fibre 3 months ago I've been unable to get a ping response from this Telecom/Spark supplied modem. It's been an annoying niggle but today became necessary that it be fixed.Had a look at the time it was installed and the often found "Allow ICMP" or "Allow ping" tickboxes found in other modems just weren't in sight.Spent a fruitless hour with the Spark frontline today but after getting cut off on the phone did make some changes to the config myself and finally got the ping response needed (I run a dynamic domain name through No-IP and want people to know that the IP has changed and see a ping response).Tried changing the ACL (Access Control List) first to enable ICMP but that didn't produce the desired results (even after create new rule, save and reboot). (Testing to see if there was any need to allow ping to work)Moved onto creating a new rule for "IP Filtering" to allow the modems internal IP address to be able to respond to WAN ICMP (Advanced / Filtering / IP Filtering)Created a rule name, changed the protocol to ICMP, no source start or end address, created a destination start and end ip address that is the modems internal ip (same ip in both start and end), selected the right interface (in my case TNZ_Fibre), and changed the Status to Accept.Still didn't work but remembering that none of my previous port forwarding attempts worked either until the modem was rebooted, did that, and my dynamic domain now responds to ping, FINALLY.Putting this out there because I couldn't find anything on the net in 15 minutes of searching that provided any info remotely close to this being required and Spark frontline and CTS weren't able to provide this either in the hour I had with them today.Hope it helps someone else get such a BASIC networking requirement working as expected.
