I recently bought two linksys routers which claim to have VPN capability. They are at two locations. Each location has a single, static IP address, and several computers behind each router.
I was hoping to learn more about how a VPN should work. Can both sides remain under the same subnet (192.168.1.1), or will one need to be 192.168.2.1.
It is asking for three fields which I am not completely sure I understand.
Local Secure Group, which accepts a host, and netmask; OR ip address; OR ip range
Remote Secure Group, which accepts a host, and netmask; or ip address; OR ip range
Remote Security Gateway, which accepts an IP address or FQDN
I'm assuming that Local Secure Group would be 192.168.x.x for whatever is behind the router it is configured on, and Remote Secure Group would be 192.168.x.x for whatever is behind the remote router, but can they be equal?
Remote Security Gateway i am nearly positive refers to the WAN IP address of the remote router.
Somebody, please clear all of this up for me.
