'ip route' is the command you're after, but you'll need to know what network(s) you're trying to get to before you can do anything meaningful with that command. -- <http://ale.cx/> (AIM:troffasky) (UnSoEsNpEaTm(a)ale.cx) 19:13:29 up 6 days, 8:25, 2 users, load average: 0.03, 0.14, 0.16 It is better to have been wasted and then sober than to never have been wasted at all

I know little about ip route but tried the following: sd route add -net 10.83.0.10 netmask 255.255.255.255 dev ppp0 and then I found that route gave: Destination Gateway Genmask Flags Metric Ref Use Iface albanetuk.guru- www.routerlogin 255.255.255.255 UGH 0 0 0 eth1 10.83.0.1 * 255.255.255.255 UH 0 0 0 ppp0 10.83.0.10 * 255.255.255.255 UH 0 0 0 ppp0 192.168.0.0 * 255.255.255.0 U 0 0 0 eth1 link-local * 255.255.0.0 U 0 0 0 eth0 link-local * 255.255.0.0 U 1000 0 0 eth1 default www.routerlogin 0.0.0.0 UG 0 0 0 eth1 default * 0.0.0.0 U 1000 0 0 eth0 Does this look hopeful?

Is there a way to make ppp0 the default? This is the kind of thing that the VPN client software [at least, every one I've ever used] will take care of for you, but, route add default gw ppp0, perhaps? Before doing that I would check that /32 route you added works. -- <http://ale.cx/> (AIM:troffasky) (UnSoEsNpEaTm(a)ale.cx) 22:07:23 up 7 days, 11:19, 2 users, load average: 0.16, 0.23, 0.18 It is better to have been wasted and then sober than to never have been wasted at all

Is there a way to make ppp0 the default? I've been in contact with the admin people for the server I'm trying to connect to. They confirm that the above albanetuk.guru ... is part of their chain, so I'm almost there. They think the problem is that I am using the local gateway instead of the remote gateway. I'm not sure what to do about that (something to do with /etc/network/interfaces?) but I'll try the route command you give here. I really can't understand why it's so difficult to do this. It's not supposed to be.
