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.
