Deployment Notes

n These procedures assume that you are already logged into the Check Point Smart Dashboard interface. The configuration tasks in this topic use version R70.1. If you are using another version, options might vary.

n NAT-T cannot be enabled on the router/firewall device. The device must have an external routeable IP address.

n This example procedures demonstrates the Check Point device in Traditional mode. Blue Coat performed limited testing in Simplified mode. You can elect to follow that procedure, which is provided inthis KB article.

n Do not send Auth Connector traffic to the Web Security Service.

Prerequisite—Verify that the device is ready for configuration.

This procedure assumes that the Check Point device is already configured with the inside interface or group object with multiple inside interfaces and an outside interface that will communicate with the Web Security Service.

STEP 1—Enable traditional mode to all new firewall policies.

1. Select Policy > Global Properties. The device displays the Global Properties dialog.

a. Select VPN.

b. Select Traditional mode to all new Firewall Policies.

2. Click OK.

STEP 2—Create a new policy package.

You cannot convert any existing simplified policy to traditional; therefore, you must manually copy the rules.
