Chapter 1 Configuring Cisco Unified Presence
Information About Cisco Unified Presence
There are two DNS servers within the internal Cisco Unified Presence enterprise deployment. One DNS
server hosts the Cisco Unified Presence private address. The other DNS server hosts the Cisco Unified
Presence public address and a DNS SRV records for SIP federation (_sipfederationtle), and XMPP
federation (_xmpp-server) with Cisco Unified Presence. The DNS server that hosts the Cisco Unified
Presence public address is located in the local DMZ.
For further information about configuring Cisco Unified Presence Federation for XMPP Federation, see
the Integration Guide for Configuring Cisco Unified Presence Release 8.0 for Interdomain Federation:

Configuration Requirements for XMPP Federation
For XMPP Federation, ASA acts as a firewall only. You must open port 5269 for both incoming and
outgoing XMPP federated traffic on ASA.
These are sample access lists to open port 5269 on ASA.
Allow traffic from any address to any address on port 5269:
access-list ALLOW-ALL extended permit tcp any any eq 5269
Allow traffic from any address to any single node on port 5269:
access-list ALLOW-ALL extended permit tcp any host <private cup IP address> eq 5269
If you do not configure the access list above, and you publish additional XMPP federation nodes in DNS,
you must configure access to each of these nodes, for example:
object network obj_host_<private cup ip address>
#host <private cup ip address>
object network obj_host_<private cup2 ip address>
#host <private cup2 ip address>
object network obj_host_<public cup ip address>
#host <public cup ip address>
....
Configure the following NAT commands:
nat (inside,outside) source static obj_host_<private cup1 IP> obj_host_<public cup IP>
service
obj_udp_source_eq_5269 obj_udp_source_eq_5269
nat (inside,outside) source static obj_host_<private cup1 IP> obj_host_<public cup IP>
service
obj_tcp_source_eq_5269 obj_tcp_source_eq_5269
If you publish a single public IP address in DNS, and use arbitrary ports, configure the following:
(This example is for two additional XMPP federation nodes)
nat (inside,outside) source static obj_host_<private cup2 ip> obj_host_<public cup IP>
service
obj_udp_source_eq_5269 obj_udp_source_eq_25269
nat (inside,outside) source static obj_host_<private cup2 ip> obj_host_<public cup IP>
service
obj_tcp_source_eq_5269 obj_tcp_source_eq_25269
nat (inside,outside) source static obj_host_<private cup3 ip> obj_host_<public cup IP>
service
obj_udp_source_eq_5269 obj_udp_source_eq_35269
