Two public IP for two independent LANs

Thu May 18, 2023 7:05 pm

Hello,

I get from ISP two public IPs assigned to MAC addresses via the one Ethernet cable. So I created additional VRRP interface (vrrp1) as an extension to the physical ether5 port. There are two DHCP client configs that gets the IP addresses from ISP. All works great, both interfaces gets proper public IP.
I created a bridge1 with some ports (ether1, ether2, ether3, wifi1, wifi2) as a LAN (with NAT, firewall etc.), so the clients in the first LAN have the normal internet connection, the WAN for this bridge is ether5.

To the ether4 there is a Cube 60Pro bridge connected with the link to other building where the CRS326-24G-2S+ switch in installed. Task is to somehow 'forward' the public IP directly to the port of the building edge switch - I've no idea how to 'bridge' the ether4 with the vrrp1.

Thanks for help!
Adam

Issue resolved by adding physical switch at the end of the ISP cable. The input port in the switch must have a STP set to 'none' as described in this topic.
