Hello all again.

I have an issue with my networking on my proxmox box. I did a fresh install on a new hard drive. I have 1 on-board nic with IP of 10.10.1.7, which is the IP of the proxmox box. I am able to get to box via the web interface. When I log on either via ssh or the box itself, I can ping 1 computer 10.10.1.14. I cannot ping my gateway, 10.10.1.1, nor anyother address locally nor can I ping out to internet. Tried to ping google....no joy.

Im a little fried right now. If I need to provide anything else please let me know.

*extra:
I have an additional 3 nics I would like to install into the new box. I have read that it is good practice to have each nic for a different pourpse. In my case I would like to have:

-eth0 (vmbr0) for proxmox
-eth1 (vmbr1) for virtual machines
-eth2 (vmbr2) for fault tolerance for vms

Since I cant even ping to gateway as it is now without fixing something, would this be possible after I can ping out onto the network?

Hi,
about don't reach the gateway: look with "tcpdump -i vmbr0 host 10.10.1.1" if you see outgoing icmp-traffic. I assume, that something on the gateway prevent the answers?
Other bridges can be configured, because you don't need IPs on the pve-host for that. It's enough if the VMs use the bridges for traffic.
