Before setting up a VPN, you must have the following:
• Two properly configured and working SOHOs or one SOHO
and one Firebox with the latest version of firmware. Each
SOHO must have the VPN option enabled.
• The static external IP address, the network address, and the
subnet masks of both devices. (The base trusted IP address of
each SOHO must be static and unique.)
• The DNS and WINS server IP address, if used.
• The shared key (passphrase) for the tunnel.
• The same encryption method for each end of the tunnel (DES
or 3DES).
