Port Forwarding is not working for me

[Editor]

Hi,

I want to forward the ports to specific VM/LXCs. To do this, `/etc / network / interfaces`
I made changes but still no redirects.

Is there a mistake here?

auto lo
iface lo inet loopback

iface enp3s0 inet manual
iface enp5s0 inet manual

auto vmbr0
iface vmbr0 inet static
        address  178.20.154.222
        netmask  255.255.255.0
        gateway  178.20.154.254
        bridge-ports enp3s0
        bridge-stp off
        bridge-fd 0

        post-up echo 1 > /proc/sys/net/ipv4/ip_forward

HAproxy	100	192.168.128.198
Web server	101	129.168.128.186
Mattermost	102	192.168.128.182

Looks good, but that requires a reboot or restart of the interface.

Does "iptables -L -t nat" list the rules ?

I restart the server after every change but still not working..
