We had an environment where all hosts reside on the same network and my LAN messenger works great. Now we have segmented our network into multiple VLANs and as expected, the LAN messenger no longer works.
We have a (slow) internet connection also, but we want the messenger to be used only for our intranet purposes (sometimes transfer huge files also). With LAN messenger, it's not a problem because the traffic never goes to internet.
Is there any messenger that works in multiple VLAN environment? Right now I have blocked intervlan communication via ACL but I can allow for specific ports used by the software.
Also, I want to mention that the clients use DHCP(Router works as DHCP Server).
