Hi all,
I've installed a router with linux (a pc with an internet connection). I
would like share this connection with the others pc on my network, but it
doesn't work. COuld anyone help me ?
two things:
1.) Have you checked "/proc/sys/net/ipv4/ip_forward"?
This must be set to "1", otherwise the router won't route any packet
2.) I don't know, what you wanna do with your chains...
My Masquerading chains (and these of many others) look a bit different:
"iptables -t nat -A POSTROUTING -i eth0 -s 10.0.0.0/24 -j MASQUERADE"
This should do it for Masqueradng the other PCs.
This my config :
eth0 (10.0.0.1) connected to internet
eth1 (192.168.0.1) connected to the rest of my lan
on my second pc (192.168.0.12), i've defined the default gateway as
192.168.0.1.
On the router, I have done the following :
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
iptables -t nat -A PREROUTING -i eth0 -j REDIRECT
When the pc tries to ping an address on the internet, there is a message
'network unreachable'
What shall I do to make it work ?
Best regards
