We have two sites connected to the Internet via a single ISP using Ethernet connections. Each site is connected to the Internet via 802.1Q tag 1364 and the sites are interconnected via 802.1Q tag 1695. Diagram attached.
Currently, the two sites use different IP address ranges but we would like to change to a flat network using a single IP address range - 192.168.0.0/24
I think I need to use Integrated Routing and Bridging but am not sure what commands to use on the local LAN interfaces without affecting traffic to the internet (Tag 1364)
I would be very grateful to anybody who could assist me.
