I've also done as Pr13sT, but that is still anoying. [NetGear 634 Router here). Luckily I'm routing all international traffic somewhere else now.
Question is if Arzy is using a router or that telkom crap. Only plus point about telkoms is that you can have more than one PPPoE session (dunno about other modems), using more than 1 account. So you end up with the option of using Linux (whohoo), more than one pc and using one as a proxy etc, or more than one session on WinXP etc.
