set ip ip-ppp restriction
{ none | admin-disabled | admin-only }
Specifies restrictions on the types of traffic the Cayman 2E-W accepts
over the PPP virtual circuit. The
none
argument means that all traffic
is accepted. The
admin-disabled
argument means that router traffic
is accepted but that administrative commands are ignored. The
admin-only
argument means that router traffic is ignored but that
administrative commands are accepted.
set ip ip-ppp addr-mapping { on | off }
Specifies whether you want the Cayman 2E-W 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.
For more information on network address translation, see “About
Network Address Translation” on page C-1.
set ip ip-ppp vj-compression { on | off }
Specifies whether you want to negotiate Van Jacobson header
compression for asynchronous PPP links. By default, TCP/IP header
compression is turned on.
When Van Jacobson header compression is turned on, your Cayman
2E-W allocates memory for 16 slots (headers) by default. The number
of slots may be reduced during link configuration if the remote peer
can only support a lower number.
set ip ip-ppp ipcp-subnet { on | off }
Specifies whether you want your Cayman 2E-W to negotiate
allocation of an IP subnet, rather than a single IP address, from a
remote access server. You should only enable this feature if you are
told to do so by your Internet Service Provider.
