For security reasons I need to forbid access to port 443 on my Gateway Router.
Only a specified list of addresses will be able to use that port.
But in order to allow PayPal IPN messages, I have to apply to the list the Paypal's ip addresses
of the servers that are used for sending IPN messages
I noticed that the server currently sending messages is the one with ip add 22.214.171.124
Quest1. : Does anyone know if this is a permanent ip? Is it possible to change after sometime?
Quest2. : Any other idea on securing port 443 without blocking PayPal's feedback (IPNs)?
PS FYI : I noticed that Paypal is sending the secure IPNs only on port 443, no matter what port you define in the
relevant field in IPN setup
