Any AirVPN users?
I configured my AirVPN connection on pfSense as outlined in their guide but with it connected I only get a quarter of my WAN bandwidth tops and often times less than that. However using the AirVPN Windows client I get my full WAN bandwidth.
Are there any AirVPN users on here who would speak to what may be the issue with my OpenVPN config?
Try executing this shell command under Diagnostics > Command Prompt:
net.inet.ip.fastforwarding = 1
It may help.
