FIX: PPTP VPN access via Telstra NextG


Overview: Corporate IP address range (eg. 10.x.x.x/24) and NextG (eg. 10.x.x.x/8) are the same. The issue arises when the PPP connection adds a default route of to PC forcing all traffic including corporate-network intended traffic through NextG route.

Resolution: Use split tunneling and have specific routes configured on VPN concentrator for all corporate subnets.


Remove the route from the routing table and reinstate after connection is dropped using scripts.
