Remote match
[remotematch] 
This setting is relevant in responder mode only. 
It is optionally filled out. In a basic configuration it is left unset. When unset, the 
SpeedTouch™ uses its dynamic IPSec policy capabilities to complete this field. The 
ipsec connection advanced 
command group allows manual control over 
this parameter.
The remotematch expresses the traffic policy for access to a remote private network 
in responder mode. It describes which IP addresses, address ranges or subnets can 
be reached in a remote private network through an IPSec Security Association. 
During the Phase 2 negotiations, the proposals of the remote peer (initiator) are 
compared with the contents of the remotematch parameter. As a result, a remote 
traffic selector is derived in compliance with the local and remote traffic policies.
The valid values for the remotematch parameter are limited to specific keywords, 
eventually followed by a network name.
The meaning of the keywords is the following:
exactly_<network name>:
The proposal issued by the remote initiator must exactly match the network 
described by the symbolic network name. This network descriptor can 
designate an individual IP address, an IP address range, or an IP subnet in the 
remote private network. If the proposal of the remote initiator does not exactly 
match the designated net, then the local responder does not establish a 
Security Association.
one_of_ <network name>:
The proposal issued by the remote initiator must contain an IP address that 
lies within the range described by the symbolic network name in order to 
successfully set up the Security Association.
subnet_of_ <network name>:
The proposal of the remote initiator must contain a subnet that lies within the 
range described by the symbolic network name in order to successfully set up 
the Security Association.
subrange_of_ <network name>:
The proposal of the remote initiator must contain a subrange that lies within 
the range described by the symbolic network name in order to successfully set 
up the Security Association.
black_ip:
The proposal of the remote initiator must contain the public IP address of the 
remote Security Gateway.
Keyword:
Followed by a Network name:
exactly_
one_of_
subnet_of_
subrange_of_
A symbolic name of a network 
descriptor, defined in the 
ipsec 
connection network
 command 
group.
