# Router
|
||||
|
||||
My little dual-NIC Arch Linux router configuration and scripts.
|
||||
Yeah yeah I need to document this better.
|
||||
|
||||
# Setup
|
||||
|
||||
```bash
|
||||
make setup
|
||||
# setup tailscale if you like
|
||||
reboot
|
||||
```
|
||||
With a fresh Arch Linux system:
|
||||
|
||||
# Update Configuration Files
|
||||
|
||||
Copies the various services' configuration files from this repo into place and
|
||||
restarts those services.
|
||||
|
||||
```bash
|
||||
make
|
||||
```
|
||||
|
||||
# System Updates
|
||||
|
||||
Should be done regularly for security reasons.
|
||||
|
||||
```bash
|
||||
make setup
|
||||
# configure tailscale as needed
|
||||
reboot
|
||||
```
|
||||
|
||||
# Quick Firewall Tweak
|
||||
|
||||
```bash
|
||||
./firewall-edit.bash
|
||||
```
|
||||
|
||||
# TODO:
|
||||
|
||||
- NixOS/declarative?
|
||||
- Install base packages as from dotfiles
|
||||
- Run `./link.fish` script
|
||||
- Enable and restart the following services:
|
||||
- `systemd-resolved`
|
||||
- `dnsmasq`
|
||||
- `nftables`
|
||||
- `systemd-networkd`
|
||||
- `dhcpcd`
|
||||
- Run `mkinitcpio -p linux`
|
||||
- Reboot
