Indian Companies uses Tally Accounting software. It supports the creation of GST bills, claiming ITC, automatic computation of tax liability, online payment of taxes.
Tally Software has Licensing model where it supports single user to multi-user mode.If you want to implement Tally in your organization, you need to have single VLAN for Client- Server Model to work. If your organization has multiple VLAN like, server VLAN is different from Client VLAN, then Tally client does not communicate with Tally server. this is known problem to the Tally, yet they have not come up with proper solution to fix this problem.
I would like to share you an solution to fix this problem.
If you have ESX server and Tally virtual server hosted on it. Create a separate Vswitch and add a dedicated physical network adapter,specify the VLAN ID for this port group which is same the client side VLAN ID
Add the Tally Virtual server network card to connect to this Vswitch. Assign the IP Address to Tally server with the same range of client PC.
Now connect the ESX host physical network adapter to the Physical switch to a port, then you have to configure the switch port to Access mode and allow the client VLAN to access this port.
Now the Client PC will be able to detect the Tally server and License will be assigned.
