I have two VLANs each with a different subnet.
We'll call them VLAN A on 18.104.22.168 and VLAN B on 192.168.16.1.
We have to maintain the network isolation for PCI (Credit Card compliance), but I have a server on VLAN A, 192.168.0.45 that computers on both VLANs need to access.
My infrastructure is three switches in series with trunking ports configured. There is a gateway for VLAN A and a separate gateway for VLAN B each to a separate router and T1 connection.
The switches are managed switches and IP routing is enabled.
Is there a way to make both VLANs communicate with 192.168.0.45?
Do I have to put both VLANs on the 192.168.0.1 subnet and just isolate by VLAN?
Is there a way to make the two VLANs communicate?
Do I need to add a static route on the switches to 192.168.045 or set the switch port that 192.168.0.45 is on as a trunk port?
This isn't my area of expertise, small business I wear a lot of hats, so any help is greatly appreciated.
