Internet Sharing & nic bridge?

Hmm...Maybe it would be easier to change IP of one of your machines to a different subclass? 192.168.1.x, for example. I don't know if it can give interesting info, put try to traceroute (in Windows tracert, as far as I know) 192.168.0.10 from 192.168.0.70 and post the result. Try it also the other way.

Oki.. now i have changed it a little bit.

Internet
||
Linux
|| \\
|| 192.168.1.2 <=> 192.168.1.10
||
192.168.0.3 <=> 192.168.0.70

With prev. configuration i couldnt get any jumps (tracert) now I get "tracert 192.168.0.70" to jump to 192.168.1.2 but then it times out. same other way.

Code:

Its swedish but it should be clear anyway (or?).

Have you tried setting the gateway to being the same as the IP of the interface it is using?

Q: which command can I use to restart eth(x)

david_ross · 03-28-2003, 06:24 PM

To add a route:
1) delete an old route first "route del 192.168.1.0" etc
2) add "route add -net 192.etc netmask 255.etc gw 192.etc"
changing etc to the rest of the ip obviously

You can restart the whole network using:
/etc/init.d/network restart

or 1 card using:
ifdown ethx
ifup ethx

I tried this but no luck =(

Code:

Now i got it to work... it was the firewall that were blocking added

Code:

$IPTABLES -A FORWARD -i $INTIF -o $INTIF2 -j ACCEPT
$IPTABLES -A FORWARD -i $INTIF2 -o $INTIF -j ACCEPT
