VLAN for Lateral Movement protection

I have a Sophos XG 105 installed, configured and connected to a 24 port switch and everything is working just fine. However, I have just seen a webinar, where it recommends creating a VLAN, rather than just connecting the XG to a switch.


so, I am just checking on the settings required to make this happen correctly. I think I have to

1) Create the VLAN (I have the article for this)
2) Create 2 firewall rules to allow all traffic to go both ways (VLAN to LAN and LAN to VLAN)
3) Change existing Firewall rules reflect this change


So, this is how things are now

Sophos XG Firewall IP Address = 192.168.10.222 (Port 1)
Switch IP Address = 192.168.10.240
LAN = 192.168.10.0


I think I need to do this

1) Create VLAN - Port 1, LAN, VLAN ID 10, IP4 Address 192.168.9.1 /24(255.255.255.0)
2) Change IP Address of XG to 9.222
3) Add 2 firewall rules to allow VLAN to LAN and visa versa

4) Change existing Firewall rules, where LAN (192.168.10.0) is being used?
