Hi! I've recently changed my ISP and my IP has changed, so I need to create a new tunnel. But when I try to create it, it gives me the error IP is not ICMP pingable. I've checked all the options on my router and I can't find a way to allow the ping. I also disabled the firewall on the router and that didn't work either. I have a TP-LINK EX230v router. Can anyone help me?
Note that you can change the endpoint IPv4 address without having to delete and recreate the tunnel. However, the address needs to be pingable. It's possible that the new ISP blocks pings. You should also try UDP pings to see if those make it to rule out unreachability.
