B-8 Virtual Private Networking

It will also be important to know the subnet mask of both gateway LAN Connections. Use the
worksheet in Appendix A to gather the necessary address and subnet mask information to aid in
the configuration and troubleshooting process.
Firewalls
It is important to understand that many gateways are also firewalls. VPN tunnels cannot function
properly if firewall settings disallow all incoming traffic. Please refer to the firewall instructions
for both gateways to understand how to open specific protocols, ports, and addresses that you
intend to allow.
Setting Up a VPN Tunnel Between Gateways
A SA, frequently called a tunnel, is the set of information that allows two entities (networks, PCs,
routers, firewalls, gateways) to “trust each other” and communicate securely as they pass
information over the Internet.
