Strange network behavior after router change

Hi all!

I am very fresh to all of this, so this is probably something simple, but I can't figure it out.

I have bought a Mikrotik HAP AX3 router/switch/AP all-in-one, so I can finally set LACP, port forwarding etc for my proxmox server.
I have set a new network in 10.0.0.0/24 with router being 10.0.0.1 and set up link aggregation to the proxmox machine. DHCP pool: 10.0.0.10 - 10.0.0.99
I have changed IP address in proxmox to 10.0.0.100, my containers are 10.0.0.*containerID*. I have changed the gateway to 10.0.0.1

I can:
ping the host from my pc in the same network
ping the host from my router
ping my computer from the host
access internet from a VM hosted on the proxmox (dhcp)
ping the forementioned VM from my computer

I can't:
ping the router from the host
ping the router from any container on the host (static ip)
ping any of the containers from my computer

What am I missing?

/etc/network/interfaces
Code:
# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

if u use vlans with your bridge u must use a separate ip config for your host.
search the forum and u will find examples. also look into the docu for part "3.3.8. VLAN 802.1Q".
I think proxmox should change the gui background function to serve this configuration because its a typical one.

Thank you for your response. For some reason my proxmox didn't like that I changed the network even though I followed documentation. I have not used vlans. I couldn't figure it out so I decided to reinstall the host and set the network to 10.0.0.0/24 during the install and it works without issues.
