How to use Multiple public IPs different VPN

[NorthernNetGuy]

Hi,

We have a 6600 r81.20 cluster, and we currently have various VPNs using our primary IP. We have multiple public IPs available in a single subnet, and are looking to have some new site-to-site VPNs use a different IP assigned to a physical interface. 

When creating a new star community, i can select the gateway, but is there a best way to select what IP or interface that should be used for the given community? or is this even a supported configuration?

Thank you

Use VSX since each Virtual System can have assigned different IP from the same subnet.

The way to determine what IP is used for VPN is Link Selection: https://sc1.checkpoint.com/documents/R81.20/WebAdminGuides/EN/CP_R81.20_SitetoSiteVPN_AdminGuide/Con... 
Unfortunately, the options are a bit difficult to work with.

R82 will have the ability to configure the Security Gateway to use different VPN interfaces in different VPN communities.
