Page 139: About Bridging
Ethernet network connected to its LAN interface from routers on networks connected to its WAN interface. When NAT is enabled, the Cayman 2E-H-W “proxies” for computers on your network by pretending to be the originating host for network communications from non-originating networks.
Page 140: Tcp/Ip Routing
Bridges let you join two local area networks, so that they appear to be part of the same physical network. As a bridge for protocols other than TCP/IP, your Cayman 2E-H-W keeps track of as many as 255 MAC (Ethernet hardware) addresses, each of which uniquely identiﬁes an individual host on a network.

MAC address and the interface appropriate for reaching that host to its bridging table. The Cayman 2E-H-W tracks the age of each entry in its bridging table, and deletes entries that aren't used after 10 minutes. If more than 255 entries are active at the same time, the Cayman 2E-H-W discards the oldest entries to make room for new ones.

Page 144: Link Establishment
Ethernet port is conﬁgured as a dial-in, dial-out, or dedicated PPP interface: Dial-in – If a port is conﬁgured as a dial-in interface, the router sends an initialization string to the modem when it is turned on to prepare it to accept calls.

Page 146 If you specify that a serial port can use either CHAP or PAP to authenticate a remote peer (that is, both CHAP and PAP are enabled), the router tries to use CHAP to authenticate connection requests. If the remote peer does not support CHAP, the router requires that the remote peer use PAP to authenticate itself.
Page 147: Network Configuration
A link can be terminated during initialization because a conﬁguration or authentication failure occurs. Once a PPP link is established, it remains conﬁgured for communication unless explicit LCP or NCP packets close the link or until some external event, such as the How Your Cayman 2E-H-W Works...
