Community rules (click to expand)

1. Follow the site-wide rules

2. Be civil
  • Understand the difference between a joke and an insult.
  • Do not harrass or attack members of the community for any reason.
  • Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
  • Bigotry will not be tolerated.
  • These rules are somewhat loosened when the subject is a public figure. Still, do not attack their person or incite harrassment.
    • 3. Post Linux-related content
  • Including Unix and BSD.
  • Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of sudo in Windows.
  • No porn. Even if you watch it on a Linux machine.
    • 4. No recent reposts
  • Everybody uses Arch btw, can't quit Vim, and wants to interject for a moment. You can stop now.
    •  

    Please report posts and comments that break these rules!

    Important: never execute code or follow advice that you don't understand or can't verify, especially here. The word of the day is credibility. This is a meme community -- even the most helpful comments might just be shitposts that can damage your system. Be aware, be smart, don't fork-bomb your computer.

    Its peer-tp-peer in that it can be configured in multiple modes on a peer by peer, interface by interface basis. You can make point to point, hub & spoke, or full mesh topologies. If you configure one of the peers for IP forwarding, it can gateway to external networks. If you configure two peers with IP forwarding and establish some routing you can build site to site topologoes, or add more peers for site to multisite and full mesh site topologies. Add IP masquerade (source NAT or PAT) to any of those topologies and it can provide remote access VPN.

    Its very flexible. Most config guides walk you through a basic remote access VPN scenario that lets remote peers access local LAN services at the one end, but not the other, and/or additionally access Internet resources via IP masquerade. The other topologies require more work, but are (edit: not) much more difficult than the remote access use case.

    Thanks for the in depth explanation.

    When I’m using it from my work laptop to work’s server to access internal sites, it feels very client -> server.

    When they said peer to peer, I was worried I was somehow also exposing my personal devices to work’s network

    I didn’t realize there were so many other ways to set it up
