move from UniFi USG

[oldfart]

Thinking of moving from the UniFi USG to OPNsense
why - I want to have a look at Intrusion Prevention (IPS) and Intrusion Detection (IDS)
However, running those on the cheaper UniFi routers has a detremental effect on their throughput!

on the entry-level model USG, WAN speed is limited to 85 Mbps,
on the USG Pro 4: WAN speed is limited to 250 Mbps
on the USG-XG-8: WAN speed is 1 Gbps (not available anymore - replaced by UDM pro)
UDM Pro - ~ 1Gbps - no reductions reported as yet
thanks to _https://freetime.mikeconnelly.com/archives/8893 for the figures

Things I think I need to change over are:
VLANS - set subnet/ip and DHCP
Firewall rules - block/allow vlan crossing
port forewarding
wireless networks - no idea

There are a few mixed posts around this forum re this but no definitive guide.
