IP-over-PPP Settings. Use the following commands to configure settings for routing IP over a vir tual
PPP inter face.
☛
NOTE:
For a DSL platform you must identify the vir tual PPP inter face [vcc n ] , a number from 1
to 8.
set ip ip-ppp [vcc n ] option { on | off }
Enables or disables IP routing through the vir tual PPP inter face. By default, IP routing is turned on. If
you turn off IP routing and save the new configuration, the Motorola Netopia® Gateway clears IP routing
settings
set ip ip-ppp [vcc n ] address ip_address
Assigns an IP address to the vir tual PPP inter face. If you specify an IP address other than 0.0.0.0, your
Motorola Netopia® Gateway will not negotiate its IP address with the remote peer. If the remote peer
does not accept the IP address specified in the ip_address argument as valid, the link will not come
up.
The default value for the ip_address argument is 0.0.0.0, which indicates that the vir tual PPP inter-
face will use the IP address assigned to it by the remote peer. Note that the remote peer must be con-
figured to supply an IP address to your Motorola Netopia® Gateway if you enter 0.0.0.0 for the
ip_address
argument.
set ip ip-ppp [vcc n ] peer-address ip_address
Specifies the IP address of the peer on the other end of the PPP link. If you specify an IP address other
than 0.0.0.0, your Motorola Netopia® Gateway will not negotiate the remote peer's IP address. If the
remote peer does not accept the address in the ip_address argument as its IP address (typically
because it has been configured with another IP address), the link will not come up.
The default value for the ip_address argument is 0.0.0.0, which indicates that the vir tual PPP inter-
face 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 [vcc n ] restrictions { admin-disabled | none }
Specifies restrictions on the types of traffic the Motorola Netopia
®
Gateway accepts over the PPP vir-
tual 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 [vcc n ] addr-mapping [ on | off ]
Specifies whether you want the Motorola Netopia
®
Gateway to use network address translation (NAT)
when communicating with remote Gateways. Address mapping lets you conceal details of your network
from remote Gateways. It also permits all LAN devices to share a single IP address. By default, address
mapping is turned “On”.
