Hello,
i'm trying to configure a server-bridge vpn on Debian 10. I follow the guide
https://openvpn.net/community-resources/creating-configuration-files-for-server-and-clients/
and bridge guide
https://openvpn.net/community-resources/ethernet-bridging/
but when i lunch the bridge-start.sh script i loss the connectivity and the lan interface keep the ip address.
ip a:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: enp3s0: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000

bridge-start.sh:
