Rule Description
Allow This rule type enables you to do the following:
• Permit outgoing access from your internal network to a specific
service on the Internet.
• Permit incoming access from the Internet to a specific service in
your internal network.
Note: You cannot use an Allow rule to permit incoming traffic, if the network or
VPN uses Hide NAT. Use an “Allow and Forward” rule instead. However, you
can use Allow rules for static NAT IP addresses.
Block This rule type enables you to do the following:
• Block outgoing access from your internal network to a specific
service on the Internet.
• Block incoming access from the Internet to a specific service in your
internal network.
