SBG3500-N000 User's Guide
DESCRIPTION
Select how the SBG3500-N authenticates a remote user before allowing access to the
PPTP VPN tunnel.
The authentication method has the SBG3500-N check a user's user name and password
against the SBG3500-N's local database, which is configured in the Maintenance >
User Account screen.
The SBG3500-N sends a Hello message after waiting this long without receiving any
traffic from the remote user. The SBG3500-N disconnects the VPN tunnel if the remote
user does not respond.
Specify the IP addresses of DNS servers to assign to the remote users.
You can choose from one of the DNS servers from the list, or choose User Defined to
enter the static IP addresses for the first and second DNS servers manually.
The WINS (Windows Internet Naming Service) server keeps a mapping table of the
computer names on your network and the IP addresses that they are currently using.
Type the IP addresses of up to two WINS servers to assign to the remote users.
Click Apply to save your changes back to the SBG3500-N.
Click Cancel to restore your previous settings.
