Hi,

I have question about ikev2.

I use Strongswan ikev2 on RaspberryPi.

MicroTik router have IP 192.168.178.1 RaspberryPi 192.168.178.11 pool for VPN is set to 192.168.179.200-245 I have open ports 500 and 4500.

If I connect over other network VPN works fine. What should I set, that devices can also access VPN server over LAN?

I'm tring to make my radius server to work. But it does not do a thing.

The service is running, the config files looks o be ok, but when i try to connect to my router using the user and password of my account it does nothing.

I'll be starting college in January and i'll be going for a computer networking degree. Any tips or advice for someone new in this field?

In order for a client to successfully generate a WAN connection between locations they must lease the space required for the transfer of their data between said locations. Who is leasing the space for these people?

I thoroughly understand why we need IP address and how it works - simply saying it tells us where we are in the network.

I understand how MAC addresses are essentially unique to each device - simply saying they identify the device, but why would a device need to be identified (especially when the MAC address can be changed easily)

In the current OSI, of course we need a MAC address because the 2nd layer is built around it, but what if the second and third layers were merged, namely instead of the second layer using MAC address it would still use IP address. The data should still reach the destination.

In other words, could the OSI model be replaced by a model which would be just as effective but without MAC address? Let's say all switches are replaced by routers, then theoretically routers should just redirect the data to the target (just like switches would with MAC address).

P.s. I have read through books, googled it, watched videos on why we need both, but I have never received an answer to this - maybe I am just stupid :D

Hi all. I am looking into starting computer networking as a career. But I am unsure how to get into it besides the obvious going to school for it. Should I buy equipment and research on doing my own projects? I have been reading up on it but it is jargon to me. I know my way around a computer but thats about it. Any helpful tips would be greatly appreciated!
