SSRS 2008 and F5 web connection problems

A = Web server B = SQL Server 2008

A = IIS is running two websites (https://web1.sample.com = 443, https://web2.sample.com = 8443) A = also runs SSRS 2008 ( = 8444, = 8445)

Background: 1. SSRS runs on A but the SSRS SQL 2008 DB is on B. OS is Win 2K8 R2 Standard. 2. and run OK on the server. We can also hit the sites from another server. 3. From a testing workstation, we can hit https://web1.sample.com and https://web2.sample.com through the F5 fine. 4. From a testing workstation, we can NOT hit and 5.We have 4 VIPs one for each URL(see above), all VIPs point to the same server just using different ports. The two IIS site are working as expected though the F5 but both the SSRS sites are not, both SSRS sites return page cannot be displayed errors. We have tried disabling IIS and setting the SSRS to listen on the know good path(the VIP and port the working IIS sites are using) but this return a 400 error.
