Connection to my router

[tarmabal]

I really cant connect proxmox to my router.

My router is in:
192.168.1.1
and I want proxmox with this network params:
address 192.168.1.250
netmask 255.255.255.0
gateway 192.168.1.1

I am really trying to set it up chaning /etc/networks/interfaces
I have even deleted all the networks and created just a eth0 static with those parameters:
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.1.250
gateway 192.168.1.1
netmask 255.255.255.0

Nothing seems to work, I cant ping the router and no pc in the same network can ping proxmox.

Can anyone help me? thanks a lot

maybe the network is defect at the link level ?
are seeing LOWER_UP when executing

ip link show dev eth0

where eth0 is the name of the device you're using for connecting your PVE host to the outside world
