Start by requesting the new DNS name and IP address from your network administrator. The IP address you request must be in the same subnet as the existing IP address on your server.
If you use proxy by hostname, be sure to request the creation of the wildcard entry to point to the same address. With proxy by hostname, you should also verify that the DNS entries with the Check DNS test.
In this note, the DNS name ezproxy.yourlib.org and the IP address 68.14.229.198 demonstrate where the DNS name and IP address should appear, and where you should insert your values instead.
These are the steps to add the second IP address to your existing network adapter.
To tell EZproxy to use this name and address, edit config.txt and add lines similar to:
Name ezproxy.yourlib.org Interface 68.14.229.198
These lines should appear before any LoginPort, LoginPortSSL, or Title lines.
Note: EZproxy is no longer supported on a server also running IIS.
