Web Campaign Forms - POST URL for Intranet Server

[SteveFD]

I want to put a lead web form on my website and have it post to my local server, can anyone point me in the right direction of what should be the value of Post URL in the following scenario?

• Sugarcrm 5.5.1RC running on a local windows domain network accessible only on the LAN via http://servername/
• Internet Site accessible by http://www.publicdomainname.com/
• I want to put a webform on http://www.publicdomainname.com/ and have the leads come through to my intranet server.
• The www server is a php hosted solution
• The intranet server is local running IIS7
• The local WAN connection has a fixed IP but port 80 is in use
• I can set the router to redirect incoming ports to my server
• I can set create a DNS 3rd domain level to access my IP if required

I have an idea to try:
Setting up a 3rd level domain sugarcrm.mydomainname.com pointing to my fixed ip (router)
Setting up a port forwarding on my router port 82 > ip of intranetserver:80
Set Post URL in lead form to http://sugarcrm.mydomainname.com:82/...bToLeadCapture

I can trial and error this to solve but I think it must be a common scenario and would rather use best practice that a best I can think of bodge.

OS Win Server 2008 R2
SugarCRM 5.5.1RC
IIS 7.5
PHP 5.2.12
MS SQL 2008 Express
