Re: Internet Connection Sharing

Slitaz network script /etc/init.d/network.sh and it's configuration file /etc/network.conf support only one (1) network adapter(nic)

Re: Internet Connection Sharing

Assuming eth0 is up on the WAN side and eth1 is your LAN side with ip 192.168.0.1/24 :

# tazpkg get-install iptables

# ifconfig eth1 192.168.0.1 up

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

# iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

Any LAN host should have a default route to 192.168.0.1 (you should launch a DHCP server to push it)

Re: Internet Connection Sharing

To setup the dhcp server, edit the /etc/udhcpd.conf file and do '/etc/init.d/udhcpd start'.

You can also update RUN_DAEMONS in /etc/rcS.conf

Re: Internet Connection Sharing

Sorry to be such a noob, but could anyone please

give me some finished examples of:

# tazpkg get-install iptables

# ifconfig eth1 192.168.0.1 up

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

# iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

/etc/udhcpd.conf

/etc/rcS.conf

to get dhcp server running on eth1 automaticly when comp starts up?

Cheers

Re: Internet Connection Sharing

Maybe try Spider Button---> System Tools ---> Configure networking. It has a DHCP tab and options there.

Re: Internet Connection Sharing

cat /proc/net/dev

tells you if you have eth1 or not, so you could modify network.sh (or better do a personal script which would not get overwritten by a system upgrade and make /etc/rcS.conf call it adding it in the RUN_SCRIPTS row) to take eth1 up and setup internet connection sharing

Re: Internet Connection Sharing

yea i was thinking of moding it so if ETH1 exists route if not then skip

or something

Re: Internet Connection Sharing

SliTaz ICS Setup

eth0 connects to WAN with cable modem

eth1 connects to LAN with switch

# [c]tazpkg get-install iptables[/c]

# [c]leafpad /etc/init.d/local.sh[/c]

Add below echo "Starting local startup commands... "

#configure interface alias connected to LAN

ifconfig eth1 192.168.0.1 up

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

#configure iptables for interface alias connected to WAN

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

# [c]leafpad /etc/rcS.conf[/c]

Add udhcpd to RUN_DAEMONS=

# [c]leafpad /etc/udhcpd.conf[/c]

interface eth1

opt dns 8.8.8.8 8.8.4.4

option subnet 255.255.255.0

opt router 192.168.0.1

opt broadcast 192.168.0.255

Reboot SliTaz ICS computer.

Reboot or restart networking on each LAN computer.
