I'm trying to use Coyote Linux (www.coyotelinux.com), which is basically Linux Router Project with an easier config script to build a floppy. I've had no problem connecting to the outside via a dialup or ethernet using DHCP, but can't quite get it to negotiate the connection to my inside network. I can get other machines running on it with no problems, as I am using static IP addresses. Any suggestions?

try ifconfig eth0 192.168.0.101

or whatever ip you need to be on the same network as the lan according to the netmask you are using.

then try to ping the other machine

ping 192.168.0.1

also...

does the light on the hub and or nic lightup when it's hooked up on the lan

do you have a firewall blocking traffic

I got Coyote Linux to connect up to the inside and outside.... now a new problem....no routing.

I don't have a firewall on inside machines, and when I request the outside network, the router dials up and connects, but doesn't route any data between my home LAN and the Internet.

Does anyone have an idea what's up?

The main thing is that you set it up to forward
run this command...

cat /proc/sys/net/ipv4/ip_forward

you should see this...

1


if not run this command...

echo 1 > /proc/sys/net/ipv4/ip_forward


you will have to put the in your firewall scripts or rc.local or somewhere that will run it when you boot if you want it to work all the time.


the other thing is your ip addresses for the internal machines, are you using ip MASQ?

if you have non-routable ip addresses like most people you will not be able to use them on the internet. You will have to always use the routers ip address. This requires ip MASQ to be set in your firewall rules


use the internet interface name in the place of ppp0 if it's not the right interface name.

for iptables...

iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE

for ipchains...

ipchains -A forward -i ppp0 -j MASQ



check the security forum or lookup rc.firewall on google.com for some rules. These are just the masq rules and should not be taken to mean that this is all you need to use.


Make sure your policies are not set to restrict all traffic
