range
start_ip_address end_ip_address
: Range for nat-policy policy type for nat-pool.
start_ip_address
specifies the beginning of the range of addresses.
end_ip_address
specifies the end of the range of addresses .
ip_address
must be expressed in dotted decimal notation for IPv4 or colon notation for IPv6.
bridge-network

range
start_ip_address end_ip_address
}
Specifies the bridge-network policy type for S-CSCF bridging.
address
ip_address_mask
: Address for bridge-network policy type for S-CSCF bridging. Specifies a
combined IP address subnet mask bits to indicate what IP addresses the specific policy type applies to.
ip_address_mask
must be specified using the form “IP Address/Mask Bits” here the IP address must be
expressed in dotted decimal notation for IPv4 or colon notation for IPv6, and the mask bits are a numeric
value, which is the number of bits in the subnet mask.

: Range for bridge-network policy type for S-CSCF
bridging.
start_ip_address
specifies the beginning of the range of addresses.
end_ip_address
specifies the end of the range of addresses.
ip_address
must be expressed in dotted decimal notation for IPv4 or colon notation for IPv6.
Usage
Generally, if a SIP packet has a VIA address (physical address that identifies where the service is located)
different from the Source address, ALG functionality is invoked. Even if the VIA and Source addresses are
the same, however, this command allows the ALG functionality to be started. For ALG to start, the VIA
address should belong to one of the nat-policy address ranges.

Example
The following command identifies the NAT policy named
policy1
with a private-address policy type of
10.10.10.10 255.255.255.0
:
nat-policy policy1 private-address address 10.10.10.10 255.255.255.0
The following command identifies the NAT policy named
policy2
with a private-address range policy type
of
172.162.23.23 172.162.23.230
:
nat-policy policy2 private-address address 172.162.23.23 172.162.23.230
The following command identifies the NAT policy named
policy3
with a default policy type:
nat-policy policy3 private-address default
