Hi all
Are there any open source firewall out there which does not require promiscuous mode to work within a HA failover cluster setup?
I am working on a cloud platform and would like to setup a failover cluster as a learning exercise but, don't want the hassle of dealing with promiscuous mode.
I did hear there was a commercial solution available maybe Palo Alto but cant be 100%
Any other suggestions greatly recieved.
Many Thanks
