  • The minivan is the peak vehicle. You can fold down or take out the back seats and fit a 4x8 panel no problem. You can travel, haul, and store till your heart is content in it. It is a car chassis so it is low to the ground but with a tall cabin so you are nice and upright. No one even looks if you sped because you have like an invisibility filter against attention. Not only that, the only knock is that it isn’t cool…which makes no sense, if getting a sports car is “compensating” then having a minivan proudly means you have nothing needing to compensate for. It is the sigma of vehicles. (2013 town and country owner)

    Are you learning networking? You’re entering the world of vlans. In the networking OSI model, Layer 3 is where you’re dipping your toes.

    I’m gonna try to over-simplify this, but each network has a gateway, which is a layer 3 device that helps a local network talk to other networks, either in the house or on the internet. That doesn’t have to be a physical device, it can be a virtual network device on your bigger layer 3 device. Most residential network gear won’t understand this. When you get into vlans, it’s like having multiple separate networks on the same devices; if you have “vlan 10” and “vlan 20”; devices on vlan 10 cannot see devices on vlan 20, even if they’re connected to the same switch. This is done by “tagging” ports, which is where you specify what network each port is on. You can also have a port with multiple vlans on it, which is called a “trunk”, but for this to work the network traffic has to carry a tag specifying what vlan each packet belongs to (though each trunk also has a “native” port, think of it like a default vlan if a packet isn’t tagged). The verbage changes based on the vendor, but that’s the idea.

    In the actual world, here’s how that works. Ports with devices on the other end with multiple devices/networks on them (access points, switches, firewalls) usually are trunks, then end client ports (your computer, a printer) are “access” ports. You would apply a single vlan to access ports, or make it an “untagged” port, whereas you “tag” multiple vlans on trunk ports. The networking devices will make most of that happen.

    So how can you shape the traffic between them? Your firewall/gateway/layer3 device. The easiest entrypoint into this is get a small computer (1L PC which you can get nearly as ewaste, having multiple network ports is good) and installing opnsense on it. It’s free and good for learning, and I use it in prod today. The opnsense box, let’s say, has 1 physical nic, then you create a virtual vlan interface on vlan 10 and 20. That becomes your “default gateway” on all client devices on the respective networks. All traffic leaving the networks go through this device (so faster network ports is better) and that is why firewall rules get to allow/block ports, IP’s, endpoints, etc. Your port forwards to the internet happen here as well. You can make a firewall rule to say your other network allows passing traffic to the original network on port 53 to the pihole, for example, so dns servers on a different “lan” can still be used.

    This is a complicated subject, but getting some gear on ebay (a “managed switch”) is a great way to learn. For example, I have an access point with a management interface on my “mgmt” vlan (99, number is arbitrary), then I have 2 ssid’s, one for IoT stuff (vlan 5) and one for my devices (vlan 4). The port going to the access point on the switch is native vlan 99 but tagged to allow traffic with packets tagged with vlan 4 or vlan 5, and the access point tags the traffic based on which SSID the client connects to, the client doesn’t care.









  • Everything you feel is valid and it is overwhelming. You can’t fix it all quickly. It will seem awful to fix. It can be fixed. When it is behind you, you will be so grateful. You can’t fix all problems now, but when you fix the last problem, you will be grateful to past you for fixing the first problem. However bad things are now, they can get worse, so realize that honestly admitting to these things now under the guise of getting help is not something you should be ashamed of. I have been there, I got past it, and everything changed. Getting my depression dealt with took years, but when it was done, it gave me the space to tolerate the discomfort of weight loss to go from 310 to 185 and to fixy career and health.

    You need a therapist, and the right one. Don’t feel embarassed if it isn’t the right fit, I went through 5 or 6 and I’ve been with mine for 10 years. You don’t need to want to get a good grade from your therapist, you won’t disappoint your therapist by having a bad week, your therapist gives you the skills to deal with the difficult things so YOU can fix your problems.

    Meds won’t fix the problems, but they will help interrupt the feedback patterns that cause feelings to amplify and seem insurmountable. The right meds will take time to find and dose right, it can take months, but it can be the enabler to help you open mental doors easier. Don’t listen to social media opinions, have an honest discussion with your care team and be open to options that have helped this process for millions of people to your own comfort level. Effexor and lexapro caused more issues than help for me, but Zoloft changed my life and after a decade I am now tapering off… Everyone has a different chemistry and understand the right mix takes time.

    You got this.
