Hi, thanks for the replies.
We have a draytek 2830n. We already have 3 VLANs set up for different departments, each VLAN is connected to the router through separate NIC ports and we have a network switch from there for our machines.
I am using the 192.168.7.x range.
We've just purchased an Antsle virtual cloud server which spins up VMs each with an IP within the 10.1.1.x range. I could always change the IPs of the VMs once they are running but thought it would be easier to use the 10.1.1.x that they are assigned.
Again, thanks for all this help
