How Do I Configure and Modify the Interesting Traffic of a VPN on the Cloud?

The number of rules that specify interesting traffic is the product of the number of local subnets and the number of customer subnets. For example, when there are local subnets A and B and customer subnets C, D, and E, the following six rules need to be configured to specify interesting traffic:

rule 1 permit ip source A destination C
rule 2 permit ip source A destination D
rule 3 permit ip source A destination E
rule 4 permit ip source B destination C
rule 5 permit ip source B destination D
rule 6 permit ip source B destination E

If you modify the local or customer subnets on the management console, the interesting traffic configuration is automatically updated. That is, ACL rules on the cloud are modified.
