Hello all,

I have Ubuntu 9.04 installed and running on a dell laptop (let's say laptop A)

(laptop A) is connected to the internet via dial-up modem and wvdial as a software

so now I have (laptop B) and I wish to connect to the internet via (laptop A) as a wifi access point, and I want to connect to it from multi-laptop, hence (laptop e, laptop c, ....) all connected to the internet via laptop A

I know it is possible by the CLI but I need some GUI interface to do this

now how to do this by both ways CLI and GUI ?

should be able to..

on laptop A

Code:

echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE

where ppp0 is your out interface..(and yeah i know its a bad way of natting)

to save so the effective changes are lost after a reboot edit the two files...

Code:

/etc/sysctl.conf:
net.ipv4.ip_forward = 1

/etc/rc.local:
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE

gui? idk.. im sure there is somewhere, but why? 2 commands and you can share your connection on a local net..

I'm trying to bridge ppp0 to eth0 without NAT.

I've done it before, and it worked great, but I don't remember how I did it, it has been 8 years...

So how to I do this?
