forgive me I am new with Linux but I am trying to setup a OpenVPN server. I have the VPN working I can ping from both the client to server and server to client. What I would like to do is masq the tun0 adapter, from the not so detailed scraps I have found from google it seems possible?

What I am using is SLES 11 and currently routing openvpn.

I want the lan to see the already configured eth0 adapter. I am only ussing one physical adapter so what I would like to do is masq/loop the tun0 adapter.

clientt 10.6.1.1 --> server 10.8.1.1(eth0) --> vpn 10.4.0.6(tun0) --> LAN network 10.8.2.1

If I do not use the vpn and only ssh I can ssh to the server (eth0) and then ssh to the LAN network already so the routes work otherwise. I need this to work with VPN though.

Ok I have not used a vpn before, but the normal way would be to do something like this hopefully when anything going out the vpn interface should have it's source changed to the address of the interface, and changed back when the packets of data return.

Are you aware of this?: http://iptables-tutorial.frozentux.n...-tutorial.html

It's a reference, perhaps the definitive reference, so it's long; but it might be helpful to you.

Thanks, this looks to be helpful.

should it read?
since I want the the tun0 packets to look like they came from eth0, that is if I am reading the document correctly

I have tried both ways and I cannot get it to work still


here is a visual diagram

WOOT!! I got it!

I used:
10.4.0.0/24 is the VPN's server address pool

Thanks again for your help.

Good to hear it's working, now I know what to do if I ever setup a vpn one day.
