Maybe someone could help me with yet again another networking issue...

Currently I am only running a public IPv6 subnet, but due to some restrictions on certain sites not supporting IPv6 (Gitlab, plex) for example I am urged to use IPv4.
So I have a public Ipv6 address configured on one of my machines and I also have an local IPv4 IP on the machine (192.168.1.2).

I also made a bridge with no interface assigned with this IP: 192.168.1.1/24. So the problem is now that I can ping the IPv4 address of my host (ProxMox) but not the gateway. What could be the issue here? Does someone know?

Here is my network config:

YAML:
auto vmbr0
iface vmbr0 inet static
        address  94.xxx.xxx.53
        netmask  24
        gateway  94.xxx.xxx.254
        bridge-ports eno1
        bridge-stp off
        bridge-fd 0

iface vmbr0 inet6 static
        address  2a02:898:x:xx::267:1
        netmask  64
        gateway  2a02:898:x:xx::1

auto vmbr2
iface vmbr2 inet static
        address  192.168.2.1
        netmask  24
        bridge-ports none
        bridge-stp off
        bridge-fd 0

iface vmbr2 inet6 static
        address  2a02:898:xxx:2::1
        netmask  64

auto vmbr3
iface vmbr3 inet static
        address  192.168.3.1
        netmask  24
        bridge-ports none
        bridge-stp off
        bridge-fd 0

iface vmbr3 inet6 static
        address  2a02:898:xxx:3::1
        netmask  64

auto vmbr1
iface vmbr1 inet static
        address  192.168.1.1
        netmask  24
        bridge-ports none
        bridge-stp off
        bridge-fd 0

iface vmbr1 inet6 static
        address  2a02:898:xxx:1::1
        netmask  64

auto vmbr4
iface vmbr4 inet static
        address  192.168.4.1
        netmask  24
        bridge-ports none
        bridge-stp off
        bridge-fd 0

iface vmbr4 inet6 static
        address  2a02:898:xxx:4::1
        netmask  64

EDIT: Alot of views but no one could help me with this 'simple' issue?

since you marked the thread as 'SOLVED' - is your issue fixed?
If yes - please share your solution - this helps all users in our community (especially those with similar problems)
If not - since all ipv4 networks are configured on bridges without network interfaces - how are you forwarding the packets out?
is ip forwarding enabled - did you setup nat?
