LAN, WAN, Wi-Fi networks

Date:2019-07-17

 

 

My adventure with nets began with quite primitive instincts. We wanted to play online with colleagues, but in times when the only network was based on BNC or connections at LPT / COM ports it required a lot of gymnastics. With time, the needs grew and knowledge also ("thank you captain obvious". This way I got to the Cisco CNA level (CCNA, but I did not do certification). I started to create VLANY-based networks, administer large WAN (BGP, OSPF) networks, including support for Internet operators based on long-range Wi-Fi (licensed bands). There was also management of UTM clusters enriched with IPS / IDS (generally understood packet inspection).
