(Solved) IPS (Suricata) kills network (programming.dev)

Hey all, I've been trying to figure out why enabling IPS kills my network. I have some services I host and would like to get some sort of IPS running. I used to have Snort running through pfSense and didn't experience issues like this.

Edit: as an update to this, I resolved it by installing the realtek plugin.

That's a good point on the memory. I actually installed with ZFS on root instead of UFS like I had on pfSense, which uses more RAM. All the hardware offloading is disabled so I think RAM is the culprit as I've only got 8gb in there.
