IP Addressing

Proper IP addressing is important when creating a VPN. To maintain scalability and performance, branch offices should use a subnet of the corporate network.

For MUVPN and RUVPN tunnels, the safest method is to define a "placeholder" secondary network, define a range of addresses for it, and choose an IP address from that network range. This allows you to draw from a range of addresses that do not clash with real host addresses in use behind the Firebox. Using this method, you must also configure the client computer to use the default gateway on the remote host.
