You cannot mix --dev tun and --dev tap on different ends of the connection. Use one or the other consistently. Most of the differences stem from the single fact that a tun-style VPN is a non-broadcast, point-to-point IP-only network, whereas a tap-style network provides a fully virtual, Ethernet-like network with broadcast support. TUN is fine for your needs.
