Customer is setting up a open XMPP Federation with cisco.com. They would like to know if a more secure solution than NAT public ip to private:5269 is available.
Can we route cisco.com XMPP traffic to VCS/Expressway 8.1.1 in DMZ and have that route to the IMP Node inside?
Reference on XMPP Federation
XMPP Federation on Expressway will be available from Expressway v8.2, which is due for release. We do not have definite date on the release but should be soon
With the new version(8.2), XMPP federation can be setup directly on the Expressway
With the current release, you can setup the XMPP federation on the IM&P server and clients logging in through MRA/Expressway will be able to communicate to federated contacts and this traffic would be through Expressway
Expressway 8.2 has been published on CCO
if you want to follow the instructions to federate using VCS-E go to the Admin Guide:
VCS/Expressway is out in version 8.2.1 with XMPP federation. Check Expressway Administrator Guide for detailed description and configuration steps.
For our deployment its working perfectly.
