How to Add Additional Interfaces to the Same Subnet

DavidPeterson

Okay, this is real simple in some other firewalls, and maybe I'm blind, but how can I add additional interfaces to the same subnet as Port 1, ie. make multiple ports like a switch?  I'm not seeing it and haven't discovered the magic terms to search on.  If I try to set up another interface it requires me to give it either an IPv4 or v6 address.  XG V16.  Thanks.

    You will need to BRIDGE the ports together.  For example, in some cases I use smaller appliances like a simple switch.  I therefore configure the LAN port (Port B) and Port C and Port D to form a Bridge (br0).  I can then assign a common subnet to the bridge.  I then assign a DHCP scope to the bridge interface and all devices attached to the bridged interfaces can communicate.

    Build a Bridge within the Network Interfaces section.

    Okay, tried to do that last night, making ports 1, 3-7 part of a bridge group, however since I'm running a high availability pair (active-passive) it wouldn't allow me to include port 1, which is of course the default LAN port, as it is one of the monitored ports for failover, which I figured would be an issue.  Any ideas?
