SRV Mobile Remote access

[luismgallop]

Hello guys, 

I'm deploying an Expressway solution version 8.7, using two different domains.

For example I have my internal domain lan.example.com and my external domain is example.com. 

My problem is when I try to log in using Cisco jabber using the external domain(example.com) I cannot resolve the automatic SRV record.

I did some packet captures on Expressway C and I saw that this server looks for SRV records _cisco-uds.example.com and cuplogin.example.com using the external domain in my internal DNS and I don't have configured in my internal DNS a zone for my external domain. 

So my question is: Is it possible to modify the Expressway C, so it looks for the SRV records using my internal domain (_cisco-uds.lan.example.com and cuplogin.lan.example.com ) instead of the external (_cisco-uds.example.com and cuplogin.example.com) ?

Thanks in advance guys,

I suggest you have a good read of the Mobile-Remote-Access-via-Expressway-Deployment-Guide-X8-7. Page 9 talks about the DNS records you need in the Public DNS space, and the Local DNS space for this to work.
