(Solved) IPS (Suricata) kills network
(programming.dev)
All discussions about the open source, FreeBSD-based firewall called OPNsense.
I don't think it's the IPS rules themselves because they were set to Alert only. I just enabled a few of the standard rule sets that are available.
I'm using a Beelink GK55 and seemed to be fine with pfSense.
As for the topology, I've got one ipv4 WAN gateway on one NIC, and the other NIC is for the LAN which connects through a couple UniFi switches. There are 3 VLANs as well.
