Need to block port 443 but still allow web access to secure sites

[Information]

My credit card vendor insists we block access to ports 23 and 443. 23 does
not affect us, as we do not need to FTP in for anything. But blocking 443
stops out IE from accessing secure sites.

How can we block 443 at the router and still access our HTTPS sites?

Thanks in advance,

Dan

I would set another simple computer (can find old Dell for $100) for the
credit card transactions and block on it port 443.
