Iskratel SI2000 Callisto 821+ routers include a very basic firewall that helps protect your home network form unwanted access from the internet. Since this firewall blocks incoming connections you may need open a port through it for certain games and applications. This process of opening a port is frequently called a port forward, since you are forwarding a port from the internet to your home network.

The basic process to open a port is:

  1. Setup a static IP address on either your computer or device that you want to forward a port to.
  2. Login to your Iskratel SI2000 Callisto 821+ router.
  3. Navigate to the port forwarding section.
    • Click the Advanced Configuration link.
    • Click on Security.
    • Click the Advanced NAT Configuration link.
    • Click the Add Reserved Mapping link.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your Iskratel SI2000 Callisto 821+ router.

Step 1

It is important to setup a static ip address in the device that you are forwarding a port to. This ensures that your ports will remain open even after your device reboots.

This step is important because you want a permanent IP address in your device. If you do not set up a permanent IP address in your device, then when you device reboots it may get a new IP address.

Use a VPN Instead

Have you considered using a VPN instead of forwarding a port? For most users, a VPN is a much simpler and more secure choice than forwarding a port.

Enter the IP address that you want to forward these ports to into the Internal IP Address box. Note that if you are forwarding ports so you can run a program on a device other than your computer then you can enter your device's IP address into that box instead.

Select the required protocol for these ports from the Transport Type dropdown box.

If you are only forwarding a single port then you can enter that same port number into the External Port Range Start, External Port Range End, Internal Port Range Start and Internal Port Range End boxes. If you are forwarding a range of ports then you need to enter the lowest number of the range into the External Port Range Start and Internal Port Range Start boxes and the highest number of the range into the External Port Range End and Internal Port Range End boxes.

Click the Add Reserved Mapping button when you are all done.

Your ports should now be open. It is time to test them.
