   @DaanHoogland the private gateway IP is configured in our VRs (Up in master 
VR and Down in backup VR). The gateway of private gateway is not configured in 
our VRs, it might be configured on some switches (of cloudstack platform or 
other platforms), similar as gateway of public IPs.

on the VR somehow doesn't feel right.

   @DaanHoogland ideally there is a network type (eg PrivateGateway) defined 
for private gateway. 
   However, it seems to be a big change in java code and python code (in vr), 
which might bring other issues.
   I prefer to fix an issue in easier and more stable way.
