It's super fast, extremely simple and considerably more performant than OpenVPN.
Now, say you’ve blocked the IP range 221.194.47.0/24 by mistake. To disable this, you can use the -n switch: iptables-L -n -line-numbers Deleting rules. Often, this is unnecessary and slows down the listing process.
iptables also tries to be helpful by doing reverse DNS lookups on the IPs.ngrok would work but the free plan is too restrictive. Dynamic DNS wasn't an option because my ISP blocks all incoming traffic. I wanted to be able to access these apps from public Internet. I wanted to be able to run some webapps on my Raspberry Pi 4B running perpetually at home in headless mode (just needs 5W power and wireless internet).
