Where remote and local address and subnet I can put for vpn configuration in linux box?
A little more information would probably be best before anyone can help you. Do you already have a VPN server/device running that you're trying to connect to? For instance, are you connecting to a specific VPN device? Or what?
If you're looking for both a VPN server/client, check out OpenVPN. It's SSL based. RPMForge has the RPMs to install the packages from. You can do a yum search to see what you can find...
yum search vpn
You can do things through IPSec as well. I suggest checking out the docs. But it's hard to say what you're looking for with the limited information you provided.
