Slow VPN? 🐌 Try these 7 quick fixes:

1. Pick a nearby, low-load server

The farther your data travels, the slower it feels. If your connection lags, switch to a VPN server closest to your real location. If your VPN offers auto-connect, let it pick the best server for you and check if that improves your speeds.

2. Change the VPN protocol

Your VPN protocol is like the lane your traffic travels in: some are faster than others. Start with WireGuard for the best balance of speed and security. If that’s blocked, try OpenVPN with UDP (good for streaming and...

DMVPN – Dynamic Multipoint Virtual Private Network 🔐🌐

DMVPN is a Cisco VPN technology designed to connect multiple branch sites securely using dynamic tunnels — without configuring point-to-point VPNs for every location.

Instead of managing hundreds of static tunnels, DMVPN builds them on demand.

How DMVPN actually works (no theory):

mGRE → Single tunnel interface, multiple dynamic peers

NHRP → Resolves private tunnel IPs to public WAN IPs

IPsec → Encrypts all traffic end-to-end

DMVPN Phases (know this for interviews):

Phase 1: Hub-and-Spoke (all traffic via hub)

Phase 2: Dynamic Spoke-to-Spoke tunnels

Phase 3: Optimized routing with NHRP redirect
