I have a proxmox with two NIC, but for some reason only one I can use.

What I want to do is setup a pfsense as firewall for all the other vms in the proxmox.

What I have tried is

1、I create a Linux bridge with no bridge ports, and pfsense attach this bridge interface. All other vms are switched to the new created bridge network, everything seems working fine except the vms has no internet access, even can’t ping wan ip but only lan ip.

2、I then create a Vlan and a bridge attach to the vlan just like the Pic shows, still the same result.

How can I make vms in the Pfsense Lan network to have internet access?

Need help!

If you using router on stick method, then you have to create 2 network for you pfsense.
1. eth1 is your pfsense wan
2. eth0 is your pfsense lan
3. then your vmbr0.100 will be your lan
post your pfsense network
