Had a few confusing occasions where I’ve altered the PPPoE MTU on remote sites to values I know work and ended up being disconnected from the site. Upon attending I found the PPPoE reporting authentication failures.
If I retype the password (looks apparently unchanged) and click apply, suddenly the connection is working again which means the action of changing the MTU fields did something to the password.
Bit of an odd one, anyone else experienced this or can Verify? v6.31 RB2011
Very annoying to have to go out to site. Not sure if safe mode would have saved me.
