## NAT Traversal Tweaks
Newt supports NAT traversal to allow clients to connect directly to Newt sites without relaying through the Pangolin server, improving performance and reducing latency.
In some environment depending on the NAT type and firewall, you may need to tweak some settings to get optimal connectivity in the firewall itself. Take a look at [these docs](https://tailscale.com/kb/1361/firewall) for some firewall changes you might be able to make.
Another option is to keep newt listening for client connections on a static port. This allows you to open a specific port in your firewall for Newt client connections instead of random high ports. You can do this by setting the `--port` flag or `PORT` environment variable and then opening this port in the your firewall to DNAT to Newt.
