KVM has no Internet?

Hello, I'm running pfSense as a KVM on hypervisor VMM 4.0.0.
I just installed another KVM Debian 12 Bookworm.
I can ping the LAN and could ping the WAN with DHCP.
Debian was on DHCP, but I changed /etc/network/interfaces to static so I can install ZoneMinder on Debian.
Anyway, here's my code as per the Debian Wiki to make a static IP.
Perhaps I'm just missing some DNS servers, but I thought the routing via the KVM router pfSense would manage the DNS?
Here's the KVM Debian terminal output below:

root@debian:~# ip -c a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

@eiger3970-0 DHCP can hand out DNS but if the device is using a static IP, DNS needs to be specified.

You can verify connectivity using an IP … ping 8.8.8.8 for example since it’s pingable.

@SteveITS yes, did the ping 1.1.1.1 and connected with DHCP, but now with the static IP, only pings LAN at 192.168.1.160, but not ping 1.1.1.1.

What does the routing table look like?

ip r

What is the pfSense network configuration?

@viragomann pfSense configuration is mentioned in 1st post, 1st line.
Host terminal output:

linuxmint@linuxmint:~$ ip r

169.254.0.0/16 dev br1 proto kernel scope link src 169.254.166.196 metric 426

So the Debian is obviously missing the default route.

The gateway in in the network config file should not be stated in CIDR notation. The mask is already given by the IP. So try to remove it from the gateway.

@viragomann Duh, 'obviously'!
Well, thanks, now the Debian KVM can ping the WAN via the KVM router.
