I'm looking for a software to route the traffic of an android app running in the Bluestacks emulator through a VPN with American/British/Australian server locations. I tried installing 7 different VPN apps in Bluestacks, but they all had connection problems, indicating a compatibility issue with the emulator.
To cut the emulator out of the equation I switched to using VPNs in the host OS (Win 10). This works for routing the browser traffic but doesn't work for the app itself (Clash of Clans). The app requires port 9339 to be open which so far none of the VPNs supported.
Is there a free VPN software that doesn't restrict port access or allows for settings to accommodate my needs? The software or (PPTP service) could also be payware if it offers a free fully functional trial.
