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 ACLs 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 ACL 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

nat (inside,outside) source static obj_host_<private cup3 ip> obj_host_<public cup IP> service

obj_tcp_source_eq_5269 obj_tcp_source_eq_35269

If you publish multiple public IP addresses in DNS all using port 5269, configure the following:

(This example is for two additional XMPP federation nodes)
