We need to immediately hire someone for the below work. We need a VPN with the following requirements: ---------- 1. We are running software on a windows pc at our office. We want our users to be able to connect to our office pc on specific ports through the VPN. For example: User 1: 100.200.300.400.500:5900 100.200.300.400.500:5901 User 2: 100.200.300.400.500:5902 100.200.300.400.500:5903 So the IP will remain the same, but different ports are assigned to specific users. If it is possible, it would be easiest if simply any authorized user could contact our office pc through the vpn on any port they specified. So if our office IP was, 123.123.123.123 and the openvpn server ip was 333.333.333.333, then if they contacted the address 333.333.333.333:5900, any data would automatically be passed to 123.123.123.123:5900. So the VPN would be acting like a simple proxy. ---------- 2. The client will be using an Android phone. ---------- 3. It is ok if all users...
