Hi Tradert. Have you looked at Advanced > Security > Firewall & DoS Protection. This is normally enabled. There are levels of detection. There doesn't look to be anything as specific as you want, to ignore an isolated ping.
Hi David. Thanks for you advice. Yes I did have a look at that and played with it but it did not make any difference as the lowest level you can set is set is 5. The problem I am having is that if I ping my wan ip address from another network the TPG modem respons to that ping, which is a security problem.
Hi Tradert. If you are not using TPGs VOIP service, you could look around for a router that can block pings altogether. It needs to support vlan tagging (setting VLAN ID=2) if you are not on FTTP.
Thanks again for your advice David. I have considered that option as well, l am using voip on the modem but if l can’t find any other solution, l might need to moved the voip to something else and try another modem.
