First of all I apologize for my english, sorry, I live in Spain and I haven't enough time to practice.
The matter is that I'm trying to establish a VPN connection between a CentOS dedicated server (GoDaddy, cPanel) as a way to share files (maybe using NFS) with a local network where all the workstations run with CentOS as well.
I've been searching and I've found that I could address the problem using either IPSec or OpenVPN. I understand the second choice a bit better, but maybe the right one will be IPSec because I already have hardware that could serve as gateway in our local network (RV042 Linksys VPN Router). I think that, if I use OpenVPN, I've to rely everything in software, is it right?
In the server, for the moment, I have only one IP address, but I'll not have problems getting one more. I also have the "tun" virtual device. In the local network I've one server (CentOS again) used as firewall and, obviously, the router to access internet.
The IP of the server is a public one (not 192.168...), I guess I'd have to create another subnet (private IPs?) and start NFS/NIS on this one, but I'm really confused about all the options.
Could you please recommend me the easiest way to do such a thing?
Thanks very much.
