Need someone besides AI to bounce your cloud networking and security questions and ideas off of? The networking subreddit r/networking is here for you.
Reddit for the Uninitiated
Reddit offers specialized communities (subreddits) where experts gather to share knowledge on niche topics. In communities like r/networking, professionals with years of real-world experience freely share their expertise.
The upvote/downvote system (impacting users’ “karma” score), helps surface high-quality information and filter out inaccurate content. This crowd-sourced quality control is particularly valuable in technical fields.
Reddit provides real-time solutions to specific problems. Rather than generic articles, you can describe your exact situation and get tailored advice from people who’ve faced similar challenges.
The platform has a searchable archive of past discussions, so you can find answers to questions that have already been addressed in detail.
The community aspect creates opportunities for ongoing discussion rather than just static information. You can ask follow-up questions and get clarification directly from experts.
Reddit also tends to be more candid than official resources, with professionals often sharing honest opinions about products, companies, and industry practices that might not be available elsewhere.
Strengths of the Networking Subreddit
The networking subreddit r/networking is a community focused on professional networking technology and enterprise network administration. It’s a place where network engineers, IT professionals, and those working with enterprise-grade networking equipment and software discuss topics like:
- Network design and architecture
- Troubleshooting complex networking issues
- Cloud networking challenges and advice
- Routing protocols (like BGP, OSPF)
- Network security configurations
- Enterprise hardware (Cisco, Juniper, Arista, etc.)
- Career advice in the networking field
The subreddit is intended for professional discussion rather than home networking questions or basic tech support, which are typically directed to other subreddits like r/HomeNetworking or r/techsupport. It serves as a valuable resource for professionals to share knowledge, ask technical questions, and keep up with industry developments.
Questions About Firewalls? Careers? NAT gateways?
A few posts to get you started:
- Is it a good idea to have different firewall vendors or just stick with one?
- Hello, i got approved 5 firewalls for my branch offices to enhance our security. We currently have two tz series Sonicwalls on our main hub and biggest branch that I have configured. I have learned a lot and feel very comfortable with them. I wanted to see if it’s a good idea to purchase from different vendors (Palo Alto, checkpoint, etc) purely so I get exposure to these new systems…
- What type of work is carried out by network security engineers?
- I am currently a network technician. I spend a lot of a time on ACLs, the role out of NAC, FIrewall Rules. procedures and documentation. It would seem that I am already, very security focused, completing vendor specific security courses for Clearpass and our firewall vendor. Is this at all grounds to change job role to a network security engineer?
- How do I configure hairpin NAT
- I am trying to figure out how to get our cpanel server to access itself from its public IP instead of its internal IP. cpanel keeps complaining when autossl trys to renew the certs because its returning its private/internal IP instead of the external IP. We are running a cisco 1941 series router on iOS 15.5(3). Here is a copy the config. Not sure how I need to change it to make this work. our cpanel server is on IP address 172.16.250.10. cpanel says we need to configure hairpin nat or loopback nat…
