What background information do I need to know?

A basic security policy will typically consist of three rules for each PLMN:

A rule for path management traffic between your local and the partner's GSNs.
A rule for securing incoming GTP traffic (i.e. a traffic of local subscribers connecting in from roaming partners.
A rule for visitor subscribers connecting their home networks.

The rules are built with these pre-defined services:

Path Management	Tunnel Management	Mobility Management
gtp_v0_path_mgmt gtp_v1_path_mgmt	gtp_v0_default gtp_v1_default	gtp_mm_v0_default gtp_mm_v1_default

Path Management

Tunnel Management

Mobility Management

gtp_v0_path_mgmt

gtp_v1_path_mgmt

gtp_v0_default

gtp_v1_default

gtp_mm_v0_default

gtp_mm_v1_default

with a Rule Base similar to this:

Source	Destination	Service	Action
Your GSNs and your partners' GSNs	Your GSNs and your partners' GSNs	gtp_v0_path_mgmt and/or gtp_v1_path_mgmt)	Accept
Your SGSNs or SGSN Handover group	Partner's GGSNs or GGSN Handover group	gtp_v0_default and/or gtp_v1_default	Accept
Partner's SGSNs or SGSN Handover group	Your GGSNs or GGSN Handover group.	gtp_v0_default and/or gtp_v1_default	Accept
