# Is port-forwarding possible in icom OS?

icom OS supports [port forwarding](https://docs.insys-icom.com/kb/docs/netfilters-en). Create a port forwarding rule as outlined below:

- Add under *Network* → *Firewall / NAT* a new Destination NAT rule.
- Configure as *Type* **Portforward**, your desired *Protocol*, the *Input interface* und last your desired *IP address* and *Port* number.
- **If your firewall is active**, add under *Network* → *Firewall / NAT* a new IP filter rule and select **FORWARD** as *Packet direction* and the *Protocol*, configure your *Input* and *Output interface*. It is very important here to set your *Destination port* and enter the *IP address* with a *Subnet mask* of **/32**.

A comprehensive configuration example can be found in this [Configuration Guide](https://docs.insys-icom.com/kb/docs/en/remote-access-to-an-ip-ready-terminal-device-via-lte-using-port-forwarding-en).
