set ip ip-ppp [ vccn ] 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 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 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 ] restriction { admin-disabled | none }
Specifies restrictions on the types of traffic the 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. The none argument means that all traffic is accepted.
set ip ip-ppp [ vccn ] addr-mapping { on | off }
Specifies whether you want the Netopia Gateway to use network address translation (NAT)
when communicating with remote routers. Network address translation lets you conceal
details of your network from remote routers. By default, address mapping is turned on.
set ip ip-ppp [ vccn ] rip-send { off | v1 | v2 | v1-compat | v2-MD5 }
Specifies whether the Netopia Gateway unit should use Routing Information Protocol (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
with MD5 authentication is an extension of RIP-2 that increases security by requiring an
authentication key when routes are advertised.
This command is only available when address mapping for the specified virtual circuit is
turned “off”.
