ISP IP change failing to apply on WG T80
As above, I have a couple of T80's in sites in Holland, connected by BOVPN, which I managed from the UK.
At one of the two sites the client's ISP has provided a new pulblic IP/DNS for our use.
The external interface is PPoE with static IP at that site. The username/password has not changed, so yesterday I updated the static IP and added the DNS server addresses, applied the change, rebooted the T80 and it fails to connect to the internet using the new ISP settings.
As an experiment I talked a colleague through setting up an old Draytek router using the same updated PPoE/static settings and it connects no problem.
I walked my colleague through changing the T80 tback o the original IP and it connected right back up to the internet. Changing it from PPoE/static to PPoE/dynamic and rebooting still shows the T80 connected on the original IP address.
So the Draytek can and will connect using the new IP/DNS PPoE/static but the WG T80 will not.
The ISP is discontinuing the old/original IP this month, so we have to move to the new IP/DNS.
I assume I have missed something fundamental - I thought all I would have to do is update the IP/DNS on the external interface and reboot.
Thanks in advance.
