Accessing ARIS 9.7 Connect Server through a reverse proxy

I need to make ARIS 9.7 Connect web server accessible from outside of my internal LAN through a reverse proxy. I have configured several systems through reverse proxies including ARIS Business Publisher with no issues but this ARIS 9.7 Connect server always seems to find a way back the client with it's internal name. Is there any special configuration required in 9.7 similar to the one suggested in this link for 7.2 (http://www.ariscommunity.com/users/bigjsko/2010-08-03-accessing-aris-outside-domain) to make it respond with "external.mydomain.com" instead of "internal.mydomain.com". Here is the extract:

**************************

3.Edit the userServerSettings.cfg (found in the ARIS server directory) to include the following:

 <profiles>

 <public options="--host aris.domainname.com" />

 </profiles>

4.stop the ARIS services;

5.ensure that adminagentsvc.exe, arisserviceenabling64 are stopped (Review the taskmgr - this sent us for a loop)

6.start the ARIS services.

***********************

Appreciate any help.

Thanks,

Madhu
