Network Sharing

ComicRack includes a network sharing functionality that allows the user to share a library completely or only selected lists. This functionality has slightly different set up if used within a LAN or over the Internet.

To enable sharing, open ComicRack, Edit menu, Preferences, Libraries tab and select “Share My Comic Library”. Here you can also select if you want to share your complete library or only select lists. You can also select to make your library editable or password protected (recommended).

Make sure you open ports 7612 and 7613 TCP/UDP on the computer sharing the library, and/or allow ComicRack through your firewall. This varies depending on the firewall software you use.

If sharing on the LAN: After you enable sharing, and restart ComicRack, if you start the program in another computer you will see a new tab with the name of the shared Library on the main program window (next to Library, Folders and Pages tabs). Clicking on it will allow you access to the shared library.

Both computers MUST be set to the same time and Time Zone in order to share your library on a LAN.

If sharing over the Internet: If the computer sharing the library is behind a router, you will need to go to the Router configuration, to a section called “Port Forwarding” (or similar, varies across brands), and create a new port forwarding for the port 7612 TCP, so that the External port 7612 is forwarded to the IP of the computer sharing the library. Check out for guides on how to forward a port in many different brands of routers

For example, if the IP of the computer sharing the library behind the router is, you will need to forward port 7612 TCP to

To connect to this shared library, open ComicRack, File menu, “Open Remote Library…” and enter the external ip address of the router. If the port forward is done correctly, you should see a new tab appear with the shared library name.

To find out the external IP, from the computer sharing the library, visit If your IP changes often, as is the case with most xDSL connections, you should set up a dynamic dns service (for example,

If you have a very large library and a slow connection, you may encounter errors when you try to click on the shared library. If it happens, try sharing only part of the library instead, by going into Edit menu, Preferences, Libraries tab and choosing only some lists instead of “Share All”.
