Description
These settings determine if and when a VPN tunnel will be established. If
network traffic meets all criteria, then a VPN tunnel will be created.
The drop-down menu allows you to configure the source IP address of the
outbound network traffic for which this VPN policy will provide security.
Usually, this address is from your network address space. The choices are:
• ANY for all valid IP addresses in the Internet address space
• Single IP Address
• Range of IP Addresses
• Subnet Address
The drop-down menu allows you to configure the destination IP address of
the outbound network traffic for which this VPN policy will provide security.
Usually, this address is from the remote site's corporate network address
space. The choices are:
• ANY for all valid IP addresses in the Internet address space
• Single IP Address
• Range of IP Addresses
• Subnet Address
AH specifies the authentication protocol for the VPN header. These
settings must match the remote VPN endpoint.
Use this check box to enable or disable AH for this VPN policy.
If you enable AH, then select the authentication algorithm:
• MD5 — the default
• SHA1 — more secure
ESP provides security for the payload (data) sent through the VPN tunnel.
Generally, you will want to enable both Encryption and Authentication. Two
ESP modes are available:
• Plain ESP encryption
• ESP encryption with authentication
These settings must match the remote VPN endpoint.
Use this check box to enable or disable ESP Encryption.
If you enable ESP encryption, then select the encryption algorithm:
• DES — the default
• 3DES — more secure
