Hello Everybody

I am trying to configure Internate Sharing using NAT (MASQUERADE).

I have linuc box with Red Hat 9.0 with two NIC. One NIC eth0 is connected to my ISP which dials out using PPTP (I am using RP-PPPOE-3.5 for ADSL connection)

I have other NIC eth1 connected to my HOME Network which gives out IP as Linux box works as DHCP server also.

After trying everything I am still unable to share the net connection.

Following are the iptables commands I Used....

1. iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE

2. iptables --append FORWARD --in-interface eth1 -j ACCEPT

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

all set OK. But while adding following route I am getting SIOCADDRT: Network is unreachable error.

route add -net 192.168.10.0 netmask 255.255.255.0 gw XXX.XXX.XXX.XXX dev eth1

where xxx.xxx.xxx.xxx is gateway provided by ISP.


Please help me in setting up the net sharing.

Thanks in Advance

hi there
i also share my internet connection but i do that using shorewall which uses IPtables
it is much easy there

also can u ping that network u want to add usig the route command

regards

Yep, I used shorewall as well, much easier to edit the shorewall config files - but now I use a separate smoothwall box. Even better...

i have heard a lot about smoothwall

but i got to know that u require a different BOX for that
which i do not have now

so i dropped the idea

That's right, smoothwall needs another box. But shorewall also works well... I used shorewall for about 6 months while I didn't have a router/smoothwall box...

Smoothwall doesn't need much to run on BTW. Any old pentium will do. Mine is a P166MMX with 32meg ram and a 1gig drive. Only need a cd, monitor and keyboard to install, then it runs headless.

Around here people throw away computers like that, but probably not in india...

I'd suggest shorewall to make things easier...

yes u r right
people do no throw away computers but they donate it to schools where a small machine will do enough good!!

and shorewall is really easy and fast!!
