LAN interface Select the LAN Interface for this rule. For example: VLAN1 or VLAN100. PPPoE Relay Status Enables an L2TP access concentrator (LAC) to relay active discovery and service selection functionality for PPP over Ethernet (PPPoE over a Layer 2 Tunneling Protocol (L2TP) control channel, to an L2TP network server (LNS) or tunnel switch (multihop node). The relay functionality of this feature allows the LNS or tunnel switch to advertise the services it offers to the client, thereby providing end-to-end control of services between the LNS and a PPPoE client. DDNS Use the Dynamic DNS (DDNS) page to specify an Internet service that allows routers with non-static public IP addresses to be located by using Internet domain names. When assigned a new IP address, the SRP updates the DDNS service to ensure that its associated domain name resolves to this new value, thereby facilitating remote access. NOTE To use DDNS, you must setup an account with a DDNS provider such as DynDNS.com or TZO.com. STEP 1 Click Network Setup > DDNS. The DDNS window opens. STEP 2 Choose a DDNS service from the drop-down list. You can choose from DynDNS.org or TZO.com. The window for the DDNS Service opens. STEP 3 Enter the information for the service that you chose as specified in the DDNS Service Settings table. Cisco SRP500 Series Services Ready Platforms Administration Guide (SRP520 Models) 80
