I have 2 ADSL lines in UK hence PPPoA (each connected to its own BM 3.8

Is there a way to get to lines concentrated, so I can use only 1 BM server?
(making it dual WAN)

Due to only 1 default gateway this is not possible with two lines attached
to 2 nics

I tried Xincom & this did not work as expected (all sorts of weired

Anybody using such setup with PPPoA (not PPPoE) - needeing ADSL modem
