PreUp/PostDown support?

[sardaukar]

Is it possible to specify PreUp/PostDown rules for an interface? Something like:

[Interface]
PrivateKey = xxxx
Address = 10.0.0.2/32
ListenPort = 51822

# IP forwarding
PreUp = sysctl -w net.ipv4.ip_forward=1
# IP masquerading (source NAT)
PreUp = iptables -t mangle -A PREROUTING -i wg0 -j MARK --set-mark 0x30
PreUp = iptables -t nat -A POSTROUTING ! -o wg0 -m mark --mark 0x30 -j MASQUERADE
PostDown = iptables -t mangle -D PREROUTING -i wg0 -j MARK --set-mark 0x30
PostDown = iptables -t nat -D POSTROUTING ! -o wg0 -m mark --mark 0x30 -j MASQUERADE

[Peer]
PublicKey = xxxx
AllowedIPs = 10.0.0.1/32

Thanks
