I have a question... if I make a VPN between differet offices that don't have the same Internet provider can I use te PPTP? Cause I know that many I-providers use the same IP address for more then one user.
You should be able to build a PPTP tunnel if you have a dedicated IP address from your ISP. Just make sure they don't use PAT or IP masking. All of the ISP's I've run by use DHCP so you shouldn't have a problem.
