Prinzipieller Aufbau:

enp0s10f0: Netzwerkinterface Richtung Internet
enp0s10f1: Netzwerkinterface Richtung Intranet
ens4: Netzwerkinterface Richtung Intranet
ens3: Netzwerkinterface Richtung Internet
enp0s10f0 (192.168.99.11) ==> hier hoert OpenVPN und bildet das Device tap0
ens3 (192.168.99.111/24) ==> hier hoert OpenVPN und bildet das Device tap0
Eine zweite OpenVPN Instanz bildet das Device tap1 (443/TCP)
-- enp0s10f0 => tap0 --+-- br0 (10.3.5.1)
-- ens3 => tap0 --+-- br0 (10.3.5.10/16)

-- enp0s10f1 ----------+
-- ens4 ----------+
```
OpenVPN Client Range: 10.3.6.1 bis 10.3.7.254 (mit PUSH gemanaged)
Hyper-V Integration:
```
Disable IPv6:
Als Network-Karte muss Legacy gewaehlt werden. Spoofing muss erlaubt sein (wegen Bridge). Zeit Synchronisation muss abgeschaltet sein.
# nmcli connection modify ens3 ipv6.method "disabled"
# nmcli connection modify ens4 ipv6.method "disabled"
```
# yum install hyperv-daemons
# systemctl enable hypervvssd
# systemctl enable hypervkvpd
```
Set end4 to unmanaged:
