just a suggestion: I know that for me, if I know where you're coming from, I can understand broken english much better. Judging from your english I'm guessing slavic, but I really have no idea.

I don't even see a question in there. The setup looks correct to me.

look..i was configure network but it`s don`t working..
i was configure it:

/sbin/ifconfig eth0 inet 192.168.1.132 netmask 255.255.255.0 broadcast 192.168.1.1

/usb/sbin/iptables -t nat -A POSTROUTING -s 192.168.1.1 -j MASQUERADE

/etc/resolv.conf

maybe am i what forget config..

/etc/resolv.conf is a file. Not sure what you mean by listing it. The contents should contain your search domains and nameservers.

Code:

search nycap.rr.com
nameserver 24.92.226.x

your iptables setup looks correct. I have a nat.sh script which does basically the same thing ->

Code:

# Delete and flush. Default table is "filter". Others like "nat" must be explicitly stated.
iptables --flush            # Flush all the rules in filter and nat tables
iptables --table nat --flush
iptables --delete-chain     # Delete all chains that are not in default filter and nat table
iptables --table nat --delete-chain

# FORWARD packets received in eth1, and ACCEPT the packet
# only needed if the default policy is DROP ?
iptables --append FORWARD --in-interface eth1 -j ACCEPT

# for packets set out from eth0, after routing, masq the packet with
# this machine's ip addess
iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE

echo 1 > /proc/sys/net/ipv4/ip_forward             # Enables packet forwarding by kernel

so looks like you're good to go.

The command netconfig might help you to configure the network. Not a network expert, but why is your broadcast ending with 1 ?

First test without iptables.
What is output of ifconfig for eth0 ?

system_elite · 12-30-2006, 04:14 PM

i must have 1 in broadcast because i have that config on windows.

I believe there is some confusion....may be what you're calling "broadcast" is actually "gateway" ?
First check how your router is set (basically if it is acting as DHCP server. Most of routers usually do as default).
If this is the case just use
/sbin/dhcpcd -d -t 15
where the -d option stands for daemon and -t 15 is the timeout setting.
If your router is configured not to act as DHCP server use
/sbin/ifconfig eth0 192.168.x.x netmask 255.255.255.0
the broadcast address will be automatically guessed by ifconfig (192.168.x.255)
To add your gateway do
/sbin/route add default gw 192.168.x.y
where 192.168.x.y is the address of your router.
Slackware comes with a very useful tool called "netconfig". This tool will make your life easier.
On /etc/resolv.conf you must add the address of the DNS servers of your IP provider. Instead you could use the addresses you find here

There are some extra small benefits
Hope this helps
