## Configuring Firewalls

Geographic Edition partner clusters communicate using transport services and ICMP echo requests and replies (pings). Their packets must therefore pass data center firewalls, including any firewalls configured on cluster nodes in partner clusters. The table below contains a list of required and optional services and protocols used by Geographic Edition partnerships, and the associated ports that you must open in your firewalls for these services to function. The ports listed are defaults, so if you customize the port numbers serving the specified transfer protocols, the customized ports must be opened instead.

Ports other than those listed in Table 4-2 might be required by storage replication services such as the Sun StorageTek Availability Suite product. See product documentation for details.
