Erm no reason I was just half asleep at the time.

just using the en5861?

No I am using the EN5861, just that we have two ADSL lines and only one
EN5861 and rather than buying another I''d like to use linux to do the
same
job as the en5861, if you know what I mean.

So far I''ve set up ppp0:0 which I''ve assigned one of the
static ip addresses
supplied to us by our ISP but when I try and route through it i.e. ip route
add default dev ppp0:0 table T1 then it returns the error no such device,
which it''s quite right there isn''t.  If I route through it
using the ip
address of ppp0:0 i.e ip route add default via x.x.x.193 table T1 then it
does work but anything that goes through it ends up using the IP address of
ppp0.

So how can I set up the linux box to use these static IP addresses in the
same way I can with the EN5861?

I hope I''d made myself clear, it''s hard trying to explain
something when
your not to sure exactly what your talking about.  Anyway any help with be
gladly received.

Cheers,

Chris.

You can, but since you have two ADSL lines, you''ll need two ADSL
devices of
some kind, whether it''s a pair of 5861s, or a 5861 and an ADSL port
adapter
(external modem, PCI card, whatever) that Linux supports.

The simplest solution will be to have the same setup for both lines.  Either
use two 5861s, or get two ADSL adapters that Linux can talk to.

So both lines were supplied by the same ISP?

If you want to remove the 5861 from the picture entirely, you''ll need
to
replace it with some sort of ADSL adapter.  You can''t just plug a DSL
line
into an ethernet card.

It would help if you could draw a diagram of your network so we could get a
better idea of what yo''re trying to do.
