これまでRaspberry Pi 3B+でSoftetherを運用してきたが、Raspberry Pi 4Bを購入したので新しく環境を構築する流れをまとめた。
Raspbianのバージョンなどは以下の通り。
pi@raspberrypi:~ $ lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 11 (bullseye) Release: 11 Codename: bullseye
pi@raspberrypi:~ $ uname -a Linux raspberrypi 6.1.21-v8+ #1642 SMP PREEMPT Mon Apr 3 17:24:16 BST 2023 aarch64 GNU/Linux
最初にネットワークブリッジの設定をしていきます。

/etc/network/interfacesの編集
pi@raspberrypi:~ $ sudo nano /etc/network/interfaces
＃書き込み禁止と出るので再起動してみる。
pi@raspberrypi:~ $ sudo reboot
再度、/etc/network/interfacesの編集
pi@raspberrypi:~ $ sudo nano /etc/network/interfaces
以下を記入
# interfaces(5) file used by ifup(8) and ifdown(8) # Include files from /etc/network/interfaces.d: source /etc/network/interfaces.d/* # Bridge interface auto br0 iface br0 inet dhcp bridge_ports eth0
再起動します。
pi@raspberrypi:~ $ sudo reboot
ブリッジが作られました。
