Cisco Setup: ROMMON Upgrade, ASDM Refresh & Multi-Context Magic

This week at Null0 Labs, we go hands-on with a real Cisco ASA 5516-X—prepping it for a future project by upgrading the ROMMON, ASA software, and ASDM. Then we dive deep into multi-context mode, turning one physical firewall into two fully isolated virtual firewalls. What’s covered: • ROMMON upgrade for bootloader stability • ASA software & ASDM refresh for modern features • Multi-context mode configuration • Context separation: interfaces, NAT, policies • Real hardware getting ready for deployment 💡 Multi-context mode lets you carve up a single ASA into multiple logical firewalls—perfect for multi-tenant environments or lab segmentation. It’s not just theory—we show it working on real gear. 0:00 Intro 4:05 Device firmware upgrade 11:00 Multi Context Setup 42:15 Outro 🛠️ Stuff I Use 🛠️ EVE-NG - multivendor network emulation software.
