[. . . ] The default value is 1492 and is used in the beginning of the PPP negotiation. In the normal negotiation, the peer will accept this MRU and will not send packet with information field larger than this value. MTU: Maximum Transmission Unit indicates the network, stack of any packet is larger than this value will be fragmented before the transmission. During the PPP negotiation, the peer of the PPP connection will indicates its MRU and will be accepted. The actual MTU of the PPP connection will indicates its MRU and will be accepted. The actual MTU of the PPP connection will be set to the smaller one of MTU and the peer's MRU. MSS: Maximum Segment Size is the largest size of data that TCP will send in a single IP packet. When a connection is established between a LAN client and host in the WAN side, the LAN client and the WAN host will indicate their MSS during the TCP connection handshake. LCP Echo Interval: Time interval that determines when a link is functioning properly and when it is defunct, detect a looped-back link and other common mis-configuration errors. LCP Echo Maximum Consecutive Failure: The maximum number of LCP Echo failures router receives before terminate the link. Authentication: When AUTO option is chosen, the PAP mode will run first then CHAP. The Conexant firmware includes the Free BSD version firewall. All UDP/TCP ports are protected from intrusion. If any specific local PCs need to be mapped to the UDP/TCP port on WAN side, please input the mappings here. 36 Public Port Start: This field allows the user to enter the start of port number for public network. Public Port End: This field allows the user to enter the end of port number for public network. Private Port: This field allows the user to enter the port number of the Private Network. In most cases, the private port number is same as public port number. Port Type: User can choose port type between TCP and UDP. Host IP Address: This field allows the user to enter the private network IP address for the particular sever. 5. 3. 6 Bridge Filtering The Bridge Filtering configuration page allows the user to set the configuration of IP filtering. User can block data from the exact MAC address or forward data to the exact MAC address. 37 Source MAC: When the bridge filtering is enabled, enter the Source MAC address, select Block and click Add. Then all incoming WAN and LAN Ethernet packets matched with this source MAC address will be filtered out. If the Forward is selected, then the packets will be forwarded to the destination PC. [. . . ] 50 6. 11 Diagnostic Test The Diagnostic Test page shows the test results for the connectivity of the physical layer and protocol layer for both LAN and WAN sides. 51 Testing Ethernet LAN Connection: This test checks the Ethernet LAN interface connection. Testing ADSL Synchronization: This test checks the ADSL showtime. If this test returns FAIL, all other tests will be skipped. Test ATM OAM Segment Loop Back: This test sends ATM OAM F5 Segment loop back request cells to the CO. [. . . ]
