# This script is for creating a bridge interface, assigning an IP address, and adding physical interface enp2s0 to it.

# Create bridge
ip link add type bridge
# name is non deterministic, fix
# Two addresses are given, one for wireguard peer and one for L2TP tunnel. Seperate addresses are required because the wireguard peer will have one route over the internet, and another route through the wireguard network.
ip address add 200.1.0.2/16 dev bridge0
ip address add 200.1.0.3/16 dev bridge0

# Change bridge0 mac address to not conflict with bridge interface of other wireguard peer
ip link set bridge0 address d6:05:05:32:d1:5d

# Add physical nic to bridge
ip link set enp2s0 master bridge0
ip link set enp2s0 up
ip link set bridge0 up

# Static Routes
# default
ip route add default via 200.1.0.1
# to reach l2tp tunnel interface through wg0
ip route add 200.1.0.4/32 via 192.168.1.2
