I have a default getway specified for my ethernet device which is
enabled and connected to an ethernet. When I dial up to another network,
using ppp, I can't do anything on that new network. I think it is
because I don't have a gateway or route set up for the new network.
Does anyone have experience setting up their route tables for multiple
networks. What do I need to do?

You need to add a new gateway through the ppp device for anything outside of
your network

I have done that using an interface to kppp. It still doesn't work. The
information is not in my routing table. I think this is the problem but I'm not
sure.

When I do this, I try something along the lines of
'route add default gw ###.###.###.###' (the ip addr of the host) and this works -
perhaps you should try something along those lines. I have used Kppp a little and
I know its quite nice - but there is no substitute for the command line :-)

That's for sure. I didn't know you can assign the default gateway on the
fly.

Did it work though :-?

No. The output was :

Quote:>/sbin/route add default gw ###.###.###.###
>SIOCADDRT: Network is unreachable

huh? I can't connect until I specify a gateway but I can't specify a
gateway until I connect????

Also

Quote:>ps -ef | grep ppp

root 3151 975 0 18:18 pts/3 00:00:00 kppp
root 3152 3151 0 18:18 ? 00:00:00 kppp
root 3153 3152 0 18:19 ttyS2 00:00:00 pppd 57600 -detach
:###.###.###.###

Well now it depends on what the network is, if it's a home network and you
don't have anything critical running, set the machine that dials out (we'll
call it "dialout") to the default gateway of your ISP, next set the other
computers on the network to use the IP of dialout as thier default gateway.
This way when the other computers want to get out to the net, they basically
ask dialout for the information, dialout retrieves the data and sends it back
to the requesting computer, ofcourse I am masq'ing the IP's in this senerio,
using ipchains.
