The environment for which we will going to implement Snow, will include the fixed users and also the roaming users. So, the fixed users will be connected to LAN so they will be in the internal zone but the roaming users will be connected to wifi and will not be always in the internal zone.
So, can we have some configuration like that a user which is currently in the internal zone should send the data to the master server which is placed in the internal zone and if it fails (roaming users will not be able to send the data because it is in internal zone) it should send data to the service gateway which will be placed in the DMZ zone and completely exposed to the internet (TCP 443). Further service gateway can send the data to the master server.
And also for some users we want to fix that they should always send the data to the service gateway and should never try to send the data to the master server.
Thanks in Advance!!!
