NAT Loopback works for HTTPS but not mail ports (993/587) — ASUS RT-AC68U limitation?
Ohhh man I had the worst thing happen to me.. it works!! (no jokes) I don't know what changed!! Like an idiot I made some final changes like turning off DDNS on the router. I'm running stock firmware too, I bought two router just to tinker. One router out of box OEM and the other Merlin. The one...- Zoolanderbot

Doesn't this only applies if the internal client is connecting using a different domain name? But in my case, I'm using the correct public domain (mail.dreblowdesigns.com), even internally. My testing is successful via telnet mail.dreblowdesigns.com 443 but fails via telnet...- Zoolanderbot

I tried turning off NAT hardware acceleration, so everything is now processed through the CPU. AiProtection was already off. Still no luck. I’m using Telnet to test local connectivity from my Mac (which is still a valid): (3.10.13) derekdreblow@MacBookPro WebSite_DreblowDesigns % telnet...- Zoolanderbot

Externally everything resolves and works fine, but locally, connections fail because internal devices try to reach the public IP, and my router doesn’t handle that correctly for all ports. I’m using an ASUS router, and it appears to support NAT loopback for HTTP (like port 80/443), but not for...- Zoolanderbot

I'm working on ChatGPT with this, and its response lol: Oof — so dig correctly resolves to 192.168.2.50, but telnet still tries to connect to 76.88.xx.xxx? That suggests your Mac isn’t actually using your router’s dnsmasq as its DNS server. What I don't understand, if it goes out to google or...- Zoolanderbot

Hey @kuchkovsky, thanks for the reply! Regardless of just the public IP or the domain host, Telnet always shows the public IP when testing, so DNS looks solid. Unfortunately the test still fails either way. If I use the local IP (e.g., 192.168.x.x), telnet connects just fine. And if I switch to...- Zoolanderbot

Hello all!! This is my first post with needing help, so here we go! I’m self-hosting multiple websites using nginx-proxy and companion NGINX containers. I also run a mail server via docker-mailserver (DMS), with acme-companion handling Let’s Encrypt certs. Everything is containerized, running...- Zoolanderbot
