PayPal being blocked seemingly by RB450 used as NAS/PPTP

Hello All,

As this is my first time using this forum I am not too sure where to begin but I am I desperately need some help from anyone that can offer it.

I am currently using an RB450 for PPtP and Radius authentication for several remote RB433 base stations. When any user attempts to connect to the internet via the remote base station slash page they are unable to get a return url from PayPal and instead receive “page timeout” responses. I checked and rechecked the configuration of the RB450 and realized that the problem is with https/ port 443. The walled gardens are all fine because they all worked prior to this issue and Authorized.net is still working perfectly but PayPal and 2Checkout is not.

I was wondering if I can receive some assistance in fixing this problem. Below is a copy of my current configuration from the RB450, thank you in advance for ANY assistance that can be offered:
