I’ve just purchased an SRX210HE2 from Ebay and planning to use it to help with my JNCIS-SEC studies.
This device is a firewall and a router and the model is listed as SRX210 Services Gateway High Memory (Enhanced performance). I chose this model as I wanted the ability to connect it to my FTTC (VDSL) connection, have the line operate at full capacity (80mbps) and be able to practice VPN configurations on the internet boundary.
You can pick this model up in Ebay for £140+, look out for what type it is as some come with extra memory, POE cards and ASDSL slots. In further posts I’ll write up my LAB topology.
