# Static Ports
For a **storage deal**, you can set a static port.
## Setup
To change the random **swarm port**, you may edit the `config.toml` file located under `$LOTUS_PATH`. The default location of this file is `$HOME/.lotus`.
To change the port to `1347`:
```sh
[Libp2p]
ListenAddresses = ["/ip4/0.0.0.0/tcp/1347", "/ip6/::/tcp/1347"]
```
After changing the port value, restart your **daemon**.
## Ubuntu's Uncomplicated Firewall
Open firewall manually:
```sh
ufw allow 1347/tcp
```
Or open and modify the profile located at `/etc/ufw/applications.d/lotus-daemon`:
```sh
[Lotus Daemon]
title=Lotus Daemon
description=Lotus Daemon firewall rules
ports=1347/tcp
```
Then run these commands:
```sh
ufw update lotus-daemon
ufw allow lotus-daemon
```
