Public IP not forwarding ports

theo66l — Thu, 29 Oct 2020 20:49:51 GMT

I have been using dynamic DNS to faciltate remote access to my BT service, without issue. However, recently (sometime since lockdown started), I have found that both SSH (on non-standard port) and VPN have both stopped working. My modem is unchanged. I have spend some time trying to find the problem on my side, and found nothing. I am now suspecting this is a BT issue.

Is there a change in the BT infrastructure causing this?

In one tracert, I found that there were 3 private IP hops before reaching a public IP. (But this is not currently the case).

Basically I would like to know if I should be contacting BT, or continue to try find the fault on my side.

Thanks,

Theo

Some Dynamic DNS services have moved to HTTPs which the home hub doesn't support. You could try a different free Dynamic DNS service to see if that works.

I have checked the Dynamic DNS. That is not the problem.

I'm using IPV4 address.
