Posted: Mon Aug 30, 2021 23:38 Post subject: Dyndns default port 80 is open
Hi everyone, I need to reach the web gui of my router remotely on a port other than 80. even disabling the remote access from "Administration-> Management", this port remains open, while the non-standard port 8888 closes. How can I avoid accessing the web management only with my dyndns.org address (80)?
My router is a Netgear r67000v3 whith firmware DD-WRT v3.0-r46854 std

Regarding port 80 being open, i assume you're referring to Enable site info being enabled, simply disable this, not sure why this is still enabled as a default setting, must be a reason but seems odd to me.
Administration>Web Access> Enable info Site Disable
or if you have had port 80 make sure you have disabled it in Remote access.
to reach your domain on a different port eg: http://mydomain.com:port
But as egc has already pointed out having ports open is not really safe and your far better running a vpn server on the router and vpn client on devices connecting to the sever. egc has written some great tuto's in sticky section https://forum.dd-wrt.com/phpBB2/viewforum.php?f=53 _________________ Netgear R7800 PPPoE Main Router

Port 80 can still be reached by disabling the option, I don't know why.

Just a stab in the dark here, but you are sure that you are seeing the open port on the dd-wrt router, instead of seeing an open port on your modem?
Dyndns is under dd-wrt, on another subnet than the isp modem.
No type of port mapping is configured on the latter
No idea if it's related or not, but I once had this problem. Both ports 22 and 80 were both opened even when they were disabled on the remote side. I had to do a full reset and manual restore in order to fix it. _________________ Linksys EA8500 (Internet Gateway, AP/VAP) - DD-WRT r48741

So your saying after a factory reset (and not restored your settings) you've disabled site info and checked UPNP is disabled (which it should be i believe after a factory reset) and you can still reach your router login page?
Is this the main router?
If so check your modem i would suggest. _________________ Netgear R7800 PPPoE Main Router
