Jabber MRA Design and Issue ( inside to outside call not working )- out side jabber to jabber is also not working

HI 

Below is the topology 

Express way nic 2 ip is 172.20.10.16 gate way to express way-E is 172.20.10.1

topology.png

 

ISP Public IP is a dynamic IP will change  but for SRV record managed with DDNS option it is able to resolve the SRV correctly

Express way is configured with dual NIC  on the lan 2 Nat ip I have to give ( PUbilic ip or ASA wan ip )  if I keep it off jabber client will not register

From Internet to Internal ext jabber call is working disconnecting in 15 sec ( both audio and video )

From Internal( EXT, Jabber) to Internet ( MRA-Jabber) it connects no audio and gets disconnect

Internet to Internet ( MRA Jabber client ) call connects no audio or video

 

 

Jabber error ( this error is captured as keeping public ip )

* Jabber logs:

Call from 2002@192.168.1.11 to 3001@192.168.1.11 failed to connect.

Further information

Jabber received 200 OK from 31.15.11.248 but the last record route of the message points to 172.20.10.16.

Jabber therefore has raised an error saying that 172.20.10.16 is an unkown address.

 

Please help what i am doing wrong on it .

 

Regards

Raja

You cannot use private IP for the NAT.

Re: Jabber MRA Design and Issue ( inside to outside call not working )- out side jabber to jabber is also not working

can we do NAT off on express-way and do only on ASA ?

 

 

But while i use the public ip on nat i am getting only 1 way call like MRA users can call the internal  user

The E Expressway doesn’t per see do NAT. What it does is to rewrite the SIP header with the IP that is set in NAT configuration. The actual NAT is done in the firewall or whatever you have that faces internet. So you’d have to use the same IP that is used for NAT in the firewall for this configuration in Expressway E.

I'm no firewall specialist, so can't really comment on you're configuration provided. It's not that hard, what ever IP that you have defined as the public IP in you NAT statement in the firewall needs to be set as the IPv4 static NAT address in Expressway. Let's say that your public IP would be 151.3.2.10, this IP should be the what you define in the NAT statement in your firewall and in this setting in Expressway. You have to use the same IP for both configurations.
