Point-to-Point Protocol over Ethernet (PPPOE)
The WAN Port of the X-50 can also be set to PPPoE. In this case, the Internet Service Provider (ISP) will supply
the administrator with a User Name and Password (most likely it will be case sensitive), which is required when
connecting the WAN port to the Internet. The ISP’s modem/gateway must be set as a bridge, allowing the X-50
system to authenticate directly with the ISP.
• Automatic (Auto) - This will automatically negotiate the correct authentication protocol.
• Password Authentication Protocol (PAP) - This will send the authentication un-encrypted.
• Challenge Handshake Authentication (CHAP) - This is more secure than the aforementioned PAP,
and sends the authentication encrypted.
• Microsoft’s version of CHAP that allows mutual authentication between peers, by piggybacking
challenge and response packets on a successful packet.
• Static DNS 1 & 2 - The Domain Name System (DNS) the Internet’s phone book, and is used to
translate IP Addresses to something that is easy to remember such as “xbluenetworks.com”.
Some Internet Service Providers (ISP) require Static DNS when using static IP Addresses.

• Enable Firewall - Although nothing is 100% safe against malicious network attacks, keeping the
firewall enabled, should minimize the effectiveness of these attacks.
