Seems like my ISP has done some "upgrades" to their setup
Now all customers needs to go through a logon page, ( portal ) to be able to get trafficflow to
go outside the local switched LAN.
All paying customers should have recieved this new pasword by postal mail, but _somehow_ they did not send it to me.
In addition, it seems like they have been starting to use NAT, feeding us with "useless" IP adresses in the
range of 10.x.x.x ( non routable adresses )
making it a real bit** to run a mailserver.
Update will be posted when/if this problems get's resolved.
