Subdomain pointing to another Windows 2012 server + using wildcard SSL certificate

Question

I have a main server "domain.com" (let's say 78.125.0.209) and a wildcard SSL certificate for this domain name. I want to use another server's subdirectory (78.125.0.210/subdir/) as a subdomain called "s1.domain.com" and use the wildcard certificate for that server too. Both servers are Windows Server 2012 R2 / IIS 8.5.

How do I achieve this?

At the moment the SSL certificate works on the main server and I have exported it to the other server as well (not tested though) but I am unable to find the right settings so that typing "s1.domain.com" on a browser would take me to 78.125.0.210/subdir/.

Answer 1

1. Add a CNAME or A record DNS entry either for "s1" or "*" that resolves to 78.125.0.210.
2. Create a new IIS site for that machine that tells IIS on that machine that the application is at the desired subfolder.
