To enable routing behind a Mobile Station perform the following steps:
Create an APN Profile
Enable or disable a Network behind Mobile Station for APN

config
context context_name
apn apn_name
end
Notes:
• The apn name must be an alphanumeric string from 1 to 64 characters in length.

config
network-behind-mobile { max-addresses-behind-mobile max_addrs | max-subnets max_subnets }
{ default | no } network-behind-mobile
end
Notes:
• default
Enables the default settings for this function. It enables NBMS with max-subnets as 10 and
max-addresses-behind-mobile as 16,777,214 default values.
• no
Disables the network behind mobile station functionality on the APN.
• max-addresses-behind-mobile max_addrs
Configures the maximum number of addresses that are allowed in a single Network/subnet Behind MS.
• max-subnets max_subnets
