Hi.

I'm configuring a Proxmox server on a notebook, using a Wifi connection. The communication is OK between on entire network.

When the firewall option on the container network configuration is off, the machine can communicate with other machines (host, containers, and other network machines).

If I enable the Network Firewall option in the Container Network menu, the container can't communicate in inbound and outbound directions. Even that I have created container firewall rules accepting inbound and outbound connections.

It occurs if the node firewall is on or off either and it occurs if the data center firewall is on or off either.

root@virt:~# pve-firewall status
vm 100 - unable to parse value of 'nameserver' - value does not look like a valid IP address
Status: enabled/running


** The "vm 100 - unable to parse value" occurs because I configure the DNS Server to 127.0.0.1#5335 to use unbound local DNS.

local hostname: virt
local IP address: 10.1.1.1
network auto detect: 10.1.1.0/24
using detected local_network: 10.1.1.0/24

I can't find where the wrong configuration is.

Try debugging with tcpdump if the problem is ingress or egress.

Hi, LnxBil. Thank you for your answer.

I did what you said:

Another machine -> ping LXC

Network Firewall Disabled:

I can see when the network interface firewall is enabled in LXC, new interfaces are created on proxmox (fwpr102p0, fwln102i0):
