Hi!,

It sounds like you want to do packet forwarding.  Make sure that the packet
forwarding is enabled in your /etc/sysctl.conf file or your
/etc/sysconfig/network file (both files are used in the Mandrake/Redhat
distributions).

You will then need to issue an instruction like:

/sbin/ipchains -A forward -i ppp0 -s 192.168.0.0/24 -d 0.0.0.0/0 -j MASQ

This will forward all packets coming in from the 192.168.0.0 network which is
on your eth0 interface to be masqueraded out the ppp0 interface.  If you are
just passing raw packets without the need for masquerading then you change the
-j MASQ to the -j ACCEPT statement.

If you use iptables rather than ipchains, you example would look something
like this:

iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE

See ya

1. Translating ARP commands from linux syntax to dos command prompt

Hi all!

Can someone please help me translating following ARP commands to dos,
so I can run then from command prompt in win98.

IPADDRESS=212.186.161.144
MODEMMAC=00:00:ca:11:fa:ee
DEVICE=eth1
FGATEWAY=10.10.10.0

arp -s $FGATEWAY $MODEMMAC -i $DEVICE
arp -s $IPADDRESS $MODEMMAC -i $DEVICE

route add -net $FGATEWAY netmask 255.255.255.0 dev $DEVICE
route add default gw $FGATEWAY dev $DEVICE

route del default gw $FGATEWAY dev $DEVICE
route del -net $FGATEWAY netmask 255.255.255.0 dev $DEVICE

Thanks a lot and greetings......Sam
