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 specific User Name and Password (most likely it will be case sensitive), which is required when
connect the WAN port to the Internet.
• 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 Static DNS address maybe required by the Internet Service Provider (ISP). If not,
the default gateway address can be used.

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