ExpressVPN requires some method of managing the network lock. Without iptables, it has no method to ensure that traffic leaves on the correct interface (ie: the VPN tunnel). https://github.com/polkaned/dockerfiles/issues/43 is a direct result of not having iptables installed.
Prior to adding iptables, any VPN clients I configured with polkaned/expressvpn as the base showed the current external IP of the network I was currently on. After adding in iptables, the clients showed an IP that depended on the VPN server connection.
