I have an ER605, and am trying to configure port forwarding to direct web traffic to my internal web server.  I've done the following:

- I have configured a domain a record to point at my public IP.

- I know this works, because when I point a web browser at this IP, the ER605 management console will load up.

- But that's not what I want; I don't want the management console of the ER605 to show up when someone hits my domain, I want the traffic routed to my internal web server.

- accordingly, I've configured a virtual server with my public ip as source and my internal web server ip as destination, and I'm forwarding port 80.

- what I expect is that when I point a web browser at my domain, it will now get forwarded to my internal web server. 
 

- BUT that is not what happens; instead the ER605 still tries to load the management console, but it gets stuck and does nothing.

I know I must be doing something wrong here, but am unsure what. I badly need to get this to work.  So, I'm wondering if someone can point out what I'm doing wrong here, and what I should be doing differently.

Many thanks in advance.
