Does Anyone know how a beginner like me in tech can start learning cyber security or starting a career in cyber engineering?

Hello

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls in two different networks.
Can anyone tell me if it's possible and, if so, give me some advice on how to set up this VPN?
Thanks in advance ^^

P.S : i'm french, so my english can be a little bit clumsy.

Hello, I am confused about whether a multi-domain SSL certificate can secure primary domains and subdomains. Can anyone clarify this for me?

when I insert ip address by clicking Network connections---> and click on Ethernet properties and change properties of IPv4--> select "use the following ip" and put ip address but as I click "ok" ip address automatically removed and the option "obtain the ip automatically " selected.
when I use ipconfig command from command prompt it shows the ip I put. I can ping other devices like printer, other PC but cannot able to give print command from my PC.

I was going fair on my Udemy networking course until I go to lesson 47. Subnetting Large Networks Part 2, my brain started smoking. Up to this point I had been dividing the network/hosts on the forth octet. And when counting the bits that I was going to borrow from the host portion of the address I wouldn't even count the bits in the network portion of the address. If it was class C I would only count the bits in the forth octet, if it was a class B I would only count the bits from bit 17 and forward/right, and if it was class A from 9 forward/right. But when I got to this lesson the instructor divides the network on the third octet and for whatever reason he started counting the network bits from the beginning, the very first bit in the first octet. I've attached the file. My network/cicso training has come to a dead stop.

Which standard to use if i want to have 4 cables for etherchannel?
IF my switches supports auto mdix, does it matter which standrad we use? Cat6 are cables.

I'm currently studying a peneteration/hacking course. I am trying to use nmap against a target to find all the ports that are filtered.

I thought if I used an ACK-scan nmap would give me all the filtered ports. I used
nmap -sA -p- target
and the result was All the 65535 ports scanned are unfiltered. Is this even reasonable? What other scans can I use to complement my first scan?

A user having a wireless connection issue on a Tp-link router has to ensure that the Internet is not dropping from the network connection side. Keep your Tp-link router away from the ovens, refrigerators, Bluetooth devices, and other electronic devices that may cause an interruption in the tplinkwifi.net network. Try Switching to the Wired connection if the issue is not resolving. Connect the router to the computer via Ethernet cable.

"I am a technology practitioner who has just entered the data communication industry. I have always hoped to increase the port speed through my efforts and achieve a smoother and stable network connection, whether it is for enterprises, operators or homes. Maybe your distance from the optimized network is just a license!
Recently I saw a very surprising technical guide, which introduced in detail the important concepts of switch licenses, and provided instructions for the use of a variety of service licenses and typical operating methods. I don't want to be the last person to know it!

Anybody here who can tell me how to send a link in Instagram chat? Of course, not as plain text, but as a link.

Thank you

Do you guys have any examples of networking terminology that some people pronounce in different ways that completely throw you off?

Similar to GIF vs JIF but networking related.

For example, there are different ways people choose to pronounce GUI, OSI, and CCIX. Any other curious examples?
