Captive Portal and PayPal Payment

[salmonbaytech]

I'm having lots of issues getting PayPal to work, I have been using PayPal & PFSense Captive portal for years but it looks like paypal is doing things differently on there end.

www.paypal.com resolves to e6616.a.akamaiedge.net
www.paypalobjects.com resolves to e4517.g.akamaiedge.net

I have added both to the hostnames to allowed hostnames but the IP's change too often for the firewall rules to keep up?

the only resolution is to restart the captive portal? and this disconnects all my users and they have to reconnect?

I hoped that by switching over to DNS Resolver vs DNS Forwarder I could easily cache DNS queries for 60 minutes and that would help the issues.

Does not seem to be the case.

Any thoughts would be appreciated.
