You probably find that it's not routing the whole network via the dialup
device..

Other words your dial up device only sees X.X.143.YY which is the dial up
server...

in your ip-up.local , try detecting that dial up connection and route the
network through it..

route add -net X.X.143.0/24 gw $5   # (or was it $6)..

try that...


I'd firstly add the route manually and see if that fixes it..

Subject: [SLUG] routing


Hi guys

At work I have my Linux laptop on the network with a static IP

X.X.105.30

When I dial-in I am given another IP address

X.X.143.187

Most things work, PROXY for websurfing, DNS, but if I wan't to access my
email thorugh sylpheed, or ping the mail server
X.X.104.13 it always trys to connect through eth0 (X.X.105.30).

If I ifdown eth0 then it only uses ppp0, which is fine unless I want to
access something via eth0.

What IPTABLES or route commands would I need to use to enable it to use ppp0
as the interface that it connects through instead ?

I have the same problem, if I use my home box for internet connection
sharing from Win 2000, via a network crossover cable to my laptop.  This
uses 192.168.0.1 for the Win 2K and an IP alias on my laptop 192.168.0.4 on
eth0:0
Obviously I can't ifdown eth0 as I lose all connectivity.

TIA

Chris
