NETGEAR FVS124G - The Role of the Local Address in VPN Tracker

The Role of the Local Address in VPN Tracker
The local address is the IP address that your Mac uses in the remote network when connected through VPN.
‣
If the Local Address field is left empty, the Mac’s actual local IP address (as shown in System Preferences > Network) is
used
‣
When Mode Config is used, the Local Address is assigned automatically by the VPN gateway
When to Set the Local Address in VPN Tracker
If Mode Config is not being used, it is beneficial to use fixed Local Addresses in VPN Tracker, instead of leaving the Local
Address field empty. Always use a fixed Local Address if:
‣
multiple clients (users/computers) use the VPN, and you cannot use Mode Config (see “Supporting Multiple Users”)
‣
the NETGEAR device is not the default gateway (router) in the remote network
Choosing the Local Address
When connecting to a NETGEAR device, the Local Address must not be part of the remote network (i.e. the
NETGEAR’s LAN) and the same Local Address may not be used by two VPN clients at the same time. If there is only
a single user of the VPN, this will often automatically be the case if the Local Address field is simply left empty, and VPN
Tracker therefore uses the Macs local IP address. However, in all other circumstances, you should configure a specific
address.

Advanced Users The Local Address is used as the endpoint of the IPsec Security Association (SA) on the VPN
Tracker side that is established in phase 2 of the connection process.
