Network Interface | Tunnels
This chapter describes the configuration of VPN tunnels. VPN tunnels can be used to secure
management and AAA traffic between the hotspot network and the network operation center of the
operator.
The Access Controllers support GRE tunnels. Furthermore PPP (Point-to-Point Protocol) can be use
to authenticate the AC to a authentication server and to assign IP settings to the WAN port of the AC.
Network Interface | Tunnels | PPPoE/GRE
Use the network interface | tunnels | PPPoE/ GRE menu to connect to ISP via PPPoE or GRE
tunnel. All traffic will be sent via this tunnel.
Default gateway specified in network interface | configuration page will not be used, because all
Internet traffic will be sent/received via the specified PPPoE or GRE server (tunnel).
By default no services are available on the controller:
