Skype for business is not supported here on QnA. I'd try asking for help in dedicated forums here.

Answer 2

Hi,
if your SfB 2015 Front-End Servers are published through a Reverse Proxy, this is the correct deployment and this URL is correct to be reachable from Internet.
If your Front-End are directly exposed to Internet via NAT, in that case you have a security issue.

That's said, I suggest to start to move your SfB users to Teams as soon as possible.
Best.
