hello dear members
i need some help. i will try to explain the scenario.
i am currently working in a office and they want to implement a software which is already designed by the vendor.
this software will provide automation of current business needs. this software as per vendor description is desinged in oracle and will only work in LAN environment.
Now here is the issue , there is a branch office located in another country and the owner wants that one client will be installed in that location so that branch office can also update records ( the vendors says this can not be done because software will work in lan )
i want to know is there any solution for this problem. we can not afford expensive solution.
i am thinking on vpn but not sure how this can help ...
can any one provide me with the solution to this problem so that both offices can use the software ? is it possible?
