Share VPN connection
Hi,
I would like to use my computer to share a VPN connection. On Debian 7.2 :
- I get my internet connection from eth1
- I am connecting to a VPN (I am using Strong VPN)
- I share my internet connection using eth0
Everything has been setup using the graphical user interface of Gnome.
If I don't connect to the VPN, everything works well, and the internet is shared through eth0. For information, here is the result of ifconfig :
eth0 Link encap:Ethernet HWaddr 50:e5:49:c5:c3:bd

Then, when I connect to the VPN, everything works well on my Debian system. But the internet is not shared anymore. For information, here is the result of ifconfig :
eth0 Link encap:Ethernet HWaddr 50:e5:49:c5:c3:bd

What can I do to solve that ?
Thanks for your help.
