Motorola Netopia 2200 Series User Manual page 222

The default value for the ip_address argument is 0.0.0.0, which indicates that the vir-
tual PPP interface will accept the IP address returned by the remote peer. If you enter
0.0.0.0, the peer system must be configured to supply this address.
set ip ip-ppp [ vccn ] restrictions { admin-disabled | none }
Specifies restrictions on the types of traffic the Motorola Netopia® Gateway accepts over
the PPP virtual circuit. The admin-disabled argument means that access to the device
via telnet, web, and SNMP is disabled. RIP and ICMP traffic is still accepted. The none
argument means that all traffic is accepted.
set ip ip-ppp [ vccn ] addr-mapping [ on | off ]
Specifies whether you want the Motorola Netopia® Gateway to use network address trans-
lation (NAT) when communicating with remote routers. Address mapping lets you conceal
details of your network from remote routers. It also permits all LAN devices to share a sin-
gle IP address. By default, address mapping is turned "On".
set ip ip-ppp [ vccn ] auto-sensing [ off | dhcp/pppoe | pppoe/pppoa ]
Enables or disables DHCP/PPPoE or PPPoE/PPPoA autosensing on the specified interface.
Setting this to DHCP/PPPoE enables automatic sensing of your WAN connection type:
PPPoE or DHCP. The gateway attempts to connect using PPPoE first. If the Gateway fails to
connect after 60 seconds, it switches to DHCP. As soon as it can connect via DHCP, the
Gateway chooses and sets DHCP as its default. Otherwise, after attempting to connect via
DHCP for 60 seconds, the Gateway switches back to PPPoE. The Gateway will continue to
switch back and forth in this manner until it successfully connects. Similarly, selecting
PPPoE/PPPoA causes the Gateway to attempt to connect by trying these protocols in par-
allel, and using the first one that is successful.
set ip ip-ppp [ vccn ] rip-send { off | v1 | v2 | v1-compat | v2-MD5 }
Specifies whether the Motorola Netopia® Gateway unit should use Routing Information Pro-
tocol (RIP) broadcasts to advertise its routing tables to routers on the other side of the PPP
link. An extension of the original Routing Information Protocol (RIP-1), RIP Version 2 (RIP-2)
expands the amount of useful information in the packets. While RIP-1 and RIP-2 share the
same basic algorithms, RIP-2 supports several new features. For example, inclusion of
subnet masks in RIP packets and implementation of multicasting instead of broadcasting.
This last feature reduces the load on hosts which do not support routing protocols. RIP-2
