Hi,

I posted previously re: XLink Kai- where we can not see nor ping our friend in the same quad of buildings.
We called the 4th level techs on our ISP and found out they intentionally block internal IPs from seeing each other.
Is there any way around this?
Some kind of software jerry-rig we can do to get around an intentional block? Thanks!
