Comment on ACLs… Closer to the Source or the Destination? by WiseAmberCedar

WiseAmberCedar — Wed, 29 Jul 2026 12:53:26 +0000

I’ve always leaned toward destination-side ACLs for simplicity, but the argument about source-side filtering cutting down on unwanted traffic across the network makes me reconsider. Doesn’t that shift also multiply the number of ACLs you have to maintain per source segment? <a href="https://nano-bananapro.com/ ">nano-bananapro</a>

Comment on NAT on Cisco ASA and ASAx Firewalls – Udemy Course by CalmEchoCanyon

CalmEchoCanyon — Wed, 29 Jul 2026 12:52:27 +0000

The point about ASA’s NAT order of operations being different from standard IOS behavior really stood out to me. I’ve been troubleshooting a PAT issue for days, and that distinction might explain why. Does the course dive into the relevant show commands for verifying each step in that sequence? <a href="https://seedance2-5.org/ ">seedance2-5</a>

I found the VLSM pen-and-paper method really helpful—do you plan to show a similar manual approach for supernetting in the upcoming live streams, or will it rely more on tools? <a href="https://nano-banana2.com/ ">nano-banana2</a>

Comment on RSA, Diffie-Hellman, DSA: the pillars of asymmetric cryptography by verityminecraft

verityminecraft — Thu, 23 Jul 2026 16:06:18 +0000

I always thought asymmetric encryption just meant public/private key pairs, so the clarification that only RSA actually does encryption while Diffie-Hellman is purely a key exchange really clicked for me. The example of the shared secret being a seed rather than a direct symmetric key also makes practical sense now.

Excellent breakdown! One of the biggest misconceptions is that all asymmetric algorithms are interchangeable Space Waves
