[SOLVED] Sharing PPTP interface between VM

[rhode]

Hi !

I'm a new user of Proxmox. I would like to create a VM on Debian 6 with openVZ which is connected to a VPN router with PPTP-linux. This VM has a new network interface called ppp0 with IP adress 192.168.168.201 (static), it has too a Venet Interface with IP Adress 10.0.0.1. I have 3 others VM with IP Adress 10.0.0.2, 10.0.0.3 and 10.0.0.4. I Would like to share ppp0 interface from the first VM to the others VM. I tried to use route protocol but it doesn't work ...

Any ideas ? Thank you in advance !

I'm sorry for my english...

Best regards
Rhode

I solved it !


I installed PPTP-Linux on the node. By a simple script executed in crontab, I make a connection to my VPN Server. I obtained a ppp0 interface with its own IP Adress.
I just needed to make iptables rules to allow traffic from VM to ppp0 interface
iptables -A FORWARD -i venet0 -o ppp0 -j ACCEPT
iptables -A FORWARD -i ppp0 -o venet0 -j ACCEPT

and


iptables -t nat -A POSTROUTING -o ppp0 -s 10.0.0.0/24 -j MASQUERADE
To rename packets from the VPN network to VM network (my VM network is 10.0.0.X and my VPN network is 192.168.2.X).

Et voilà !

Thank you very much for Proxmox OS, it's wonderful !
