Hi,

a quick and faster temporary fix is to restart you wan interface, that re-initates the connection. Check what you are using to monitor the link and disable it for a while to see if that fixes the issue.

Hi Noel,

I was talking about link monitoring within the XG, if it thinks the link is down regardless it will stop any connections. I know there is a bug in the IPv6 process, but had not had any issues with IPv4 except when it is on the link that also has IPv6 enabled.

Hello

I had a similar issue, constant WAN drop outs at random times. I did manage to track down the problem.

I had upgraded the firmware on a DrayTek Vigor modem, and the in this process the MTU on the modem was changed. This created an MTU miss-match between the modem and the XG.

Setting both MTU values to the correct, and matching, value solved the issue.

I hope this helps.
