VIP's causing issues trying to navigate to webpage. (6.4.8)

[cresendiz]

Hello all 

I had a weird issue where a company reached out to me to open a few ports from the wan to a computer in the lan. 

i created the VIP's under policies and objects and pointed each port from the wan IP to the internal private ip. i then applied the newly created VIP's to a policy going from the WAN interface to the LAN interface. i got calls saying the website was no longer accessible. i turned off the policy but the website was still unavailable. it was only after i deleted the VIP's completely from the firewall that the website was available again. 

my question is why is the website access still an issue after the VIP's are removed from all policies?
