I am trying to figure this out.
Basically the virtual IP 192.168.1.110 will filter port 80 to the real ip address 192.168.20.110. I can confirm this in the logs.
When I click any link on the page (in wordpress if that matters), it will follow the link on the page www.domain.com/help.
If I type in 192.168.1.110/help it will route correctly.
I tried to create a service rule to filter: Domain - * URL - /* Extended Match - *
I have also tried with more specific values.
Note: This environment is hosted on my workstation. I do not have access to the DNS server (if needed). I assume I can make use of host files or the Barracuda WAF host files.
Thanks.
