Ok so I eneded up putting a switch between the two,
I know that LACP provides fault tolerance and load balancing but it will not increase my bandwidth, each link will be treated separately, if I wanted to increase bandwidth I would use a round robin scheduler on both ends.
The reason I have lacp between both pfsense boxes is to provide another link to load balance tcp connections as well as vpn traffic through.
The main reason I posted my question was to find out whether pfsense could be set to setup a LACP link between two pfsense boxes without additional hardware. I soon found out that this was not possible.
And yes a seperate IDS on each box. After adding the switch to my network design this has opened up a third location to stick an IDS
Kind Regards.
