@stephenw10 Very interesting, im going to read up on this some more.
I did put the pfsense box on full WAN duty, its just connected to the forti with a /30 private link. Performance is great, without much tweaking I was able to get full speeds up and down, CPU usage was even at 18-19% for both tests. I might just stick to this anyway, maybe ditch my forti until I buy the 60F, id rather just deal directly with the box that holds the WAN address.
I appreciate the help Steve.
