Patent ID: 8458344

Claim:
A method comprising: by a first computing device, receiving a first communication packet from a second computing device destined to a third computing device; if the first communication packet is a connection-initiating packet having no customization indicator, then: generating a second connection-initiating packet having a customization indicator and addressed to the third computing device; setting a value of the customization indicator of the second connection-initiating packet to 0; and sending the second connection-initiating packet to the third computing device; if the first communication packet is a connection-initiating packet having a customization indicator with a value of 0, then: generating a third connection-initiating packet having a customization indicator and addressed to the third computing device; setting a value of the customization indicator of the third connection-initiating packet to 1; and sending the third connection-initiating packet to the third computing device; if the first communication packet is a connection-initiating packet having a customization indicator with a value of 1, then: generating a first connection-acknowledgement packet having a customization indicator and addressed to the second computing device; setting a value of the customization indicator of the first connection-acknowledgement packet to 1; and sending the first connection-acknowledgement packet to the second computing device; if the first communication packet is a connection-acknowledgement packet having no customization indicator, then: installing an intercept rule; generating a second connection-acknowledgement packet having a customization indicator and addressed to the second computing device; setting a value of the customization indicator of the second connection-acknowledgement packet to 1; and sending the second connection-acknowledgement packet to the second computing device; and if the first communication packet is a connection-acknowledgement packet having a customization indicator with a value of 1, then: installing a bypass rule.
