Implementationīefore proceeding, ensure NAT loopback actually doesn’t work with your version of DD-WRT. Then, follow this tutorial to allow NAT loopback. The simplest solution to this is, as usual, to flash DD-WRT to your router. However, this is not an intentional barrier, it’s just a constraint of limited stock firmware. The primary reason for the security concern is that some consumer routers appear to intentionally disable NAT loopback by default, and there is no way around this with stock firmware. We’re still talking about NAT loopback, right? The internet has made us so gullible … Coincidentally, the posts never specify why the claims might be true, lack credible sources, and are rarely found outside of back alley forums. Your router will not stab you in your sleep if you allow NAT loopback … although it may emit higher levels of radiation, lace your lipstick and food with carcinogens (compliments of the government, of course), and kill Brad Pitt. Like the vast majority of scare tactic-based content on the internet, it’s false. Don’t be fooled by the plethora of forum posts crying that NAT loopback is disabled on routers purposefully, that it opens up dangerous security holes, or that it will destroy your network and ultimately your livelihood as you know it. NAT loopback is needed to accomplish this, and it is simple and safe. If you’re like me, you simply want internal and external access to operate in the same way. There are any number of valid reasons why you’d want to allow NAT loopback on your network. Internally, if NAT loopback is disabled or blocked, you would not be able to access this the same way. From an outside network, you could simply visit your external IP address from a browser to access the web server. For instance, say your router forwards port 80 to a web server on your LAN. SERVER: 192.168.1.253#53(192.168.1.NAT loopback is what your router performs when you try to access your external IP address from within your LAN. flags: qr rd ra QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: >HEADER<<- opcode: QUERY, status: NOERROR, id: 23772 13Ĭurrently my dns server asks the roots and returns the public IP Well if my router does not support loopback, I could just use a host file to point to 192.168.1.13, or I could setup my local name server to point to it so all devices on my local network resolve to. Now if router supported nat reflection I could access 216.34.181.48 and since I have a forward setup my router would send me back into. Say I was hosting that site on a box on my my network 192.168.1.13 for example. flags: qr rd ra QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 >HEADER<<- opcode: QUERY, status: NOERROR, id: 21492 So I quickly created an example using my local dns, that all devices on my network use. You are clearly running some server you need access to from the outside and inside, so this "server" could be your dns - you could run bind on it for example, or whatever other dns server you want, unbound is good, etc. You mean if you take your device outside your lan, yeah that would be a problem - if the device leaves your local network, then use dns.Īgain I currently don't have time to read your routers manual for you, or its capabilities for DNS.
