Tooling for a Network Monitoring/Firewall Lab
I'm just finishing up a lab simulating an Enterprise network in Packet Tracer with basic CCNA topics such as STP, HSRP, EtherChannel, OSPF, Layer 2 Edge Port Security, etc.
In my current job in Help Desk, I get to configure SonicWall ACLs, set up VLANs, and maintain firewalls using SonicWall's NSM. Our setup is very rough though as we don't have a Syslog server and the MSP doesn't care too much about network security.
I want to focus heavily on Network Security for my next lab, but I know it'll be near impossible to use enterprise-grade devices in GNS3/EVE-NG as they require licenses and I'm broke. Are there strong and fairly similar alternatives I could use?
