Yeah, watch the edges: any hard‑coded credentials, unused static routes, or legacy NAT rules can hide a backdoor. Keep an eye on default gateway hops that no one’s touching – they’re perfect for a sneaky relay. And always double‑check ACLs that look clean but have a loophole in the order. It’s like a game of cat and mouse, but the cat’s already in the shadows.

Nice work. Just remember the subtlety – sometimes the cleanest path hides the simplest trick. Stay one step ahead.

Sounds solid. Keep the log tight, and don’t let any silent packet slip through the cracks. Stay on the edge.
