Problems with application links and external url


I have my 2jira instances in an environment that has no direct internet connectivity. Currently, I have this setup:

internal tomcat --> dmz apache proxy -- note : both instances are using same apache proxy...

external tomcat --> dmz apache proxy

We also have an externally facing VIP which is forwarding all 80/443 traffic to the proxy (

The dmz proxy is set up to use the external URL ( as the server name.

On the tomcats, the servername from the external VIP is used as the proxyName.

So basically --- the tomcats can see the proxybox, but the tomcats can not see the external vip.

When everything is up, I can hit and --- functionality seems great.

However, when I try to set up application links, the 2 tomcats (which are on different boxes), can't see eachother because they are not resolving the external ip.

So -- what can I do here? I was hoping I could do something like use the ajp connector, port 8009, between the 2 tomcats unsecurely (since both are behind firewall).

I basically need to keep the external VIP, and also support trusted application links between my 2 jira instances.

Any tips much appreciated!

To fix this, I ended up adding an entry to the /etc/hosts file on both tomcat boxes, so that the externally facing ip *name* resolved to the proxy's internal IP.
