Debian 13 更改網路卡別名

編輯 /etc/systemd/network/10-eth1.link

[Match]
MACAddress=00:11:22:33:44:55

[Link]
Name=eth1

方法二 UDEV設定方式
編輯 /etc/udev/rules.d/10-rename-it.rules
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="00:11:22:33:44:55", NAME="eth1"
Debian 網路命名規則通常在開機 initramfs 階段就決定，須更新 initramfs

Shorewall Hairpin NAT 或 NAT Loopback 設定方式

fw eth2:192.168.119.253/24
ap eth2:192.168.119.231/24:3142

編輯 /etc/shorewall/interfaces
增加內網介面 routeback 選項( Shorewall 會丟棄在同一個介面「進又出」的封包)
loc eth2 dhcp,routeback

編輯 /etc/shorewall/snat (偽裝來源，讓伺服器以為是「防火牆」在找它)
SNAT(192.168.119.253) 192.168.119.0/24 eth2 tcp 3142 -

編輯/etc/shoreall/rule (定義轉發：當內網存取fw ，目標轉向伺服器)
DNAT:NFLOG(4) loc loc:192.168.119.231 tcp 3142 - -
