This property specifies policy filters for non-local source routing. The filters consist of a list of IP addresses and masks which specify destination/mask pairs with which to filter incoming source routes. Policy filters are defined like this:

Session.AdvancedOption.PolicyFilter="192.168.1.1,255.255.255.0,195.29.212.243,255.255.255.248" ' IP address, corresponding mask, another IP address, corresponding mask

Any source routed datagram whose next-hop address does not match one of the filters should be discarded by the client.
