[SOLVED] Network at host (Proxmox) isn't working

I have installed my Proxmox host in a extra network where no internet access exist.
There I configurated Proxmox and managed the network cards.

At this time I have 1 network card with 2 Lunix Bridges
These two Bridges are for my VLANs
1st vlan: management-network, so no internet access
2nd vlan: normal network with internet access.

At fist I wasn't even able to ping 8 .8.8.8
Now i added the DHCP Server to the Linux Bridge (2nd vlan) at "gateway".
Now I am able to resolve names like www . google . com (without spaces)

But I am not able to receive packets.
In all VMs (installed Linux Bridge 2nd vlan) all pings and other connections to the internet are working.

I have no idea what config file is wrong. I assume the whole problem is because I configurated the whole host in an isolated network.
where do you get no packets? In the VM or on the host?
On the Host.

The VMs are working fine.
On the VMs the time is correct, ping to a webserver is possible and browsing too.
The host itself has a wrong time and isn't able to get response from any ping outside the network

Got it. wrote dhcp server ip-address in gateway. Should simply used our gateway-server - ip-address
