Concerned about seeing my modem when typing in my public IP address

@psherman

Does this happen from outside the network, or only from within?

Only from within. Still extremely dangerous due to the things I said before. Clients on guest wifi should NEVER get access to the modem page under any circumstances imo.

@psherman

This isn't inherently an OpenWrt problem, so I'm not sure how the development team here would be able to solve it. You should report this to your ISP or the manufacturer of the modem.

True but I think OpenWRT should protect users against dumb ISPs and manufacturers out of the box.

@psherman

No, this wouldn't work the way you think it would... it's never that simple and you'd likely break other things.

Works for me. Been doing this for a month with no issues. I'm happy that clients on the guest wifi can't access the modem.

@psherman

I can't speak for the devs, but probably not, as many people actually want to be able to use their public IP as a way of reaching internal services that are port forwarded (even from within the LAN). And the problem is not universal or even common

It's actually a quite popular concern that gets discussed here from time to time for example:

Block access from outside LAN

I'm going crazy, i have a public ip address that can be used to access my router LUCI and SSH. In the general firewall settings i've already set Input: reject but still seems like that i can access to my router from my external IP address. Is there anything i can do to block access from WAN and allow only from LAN?

@psherman

it is an issue with your modem, not your router.

If you read the link I posted on my original post you can see that other users replied to me saying it's "normal Linux behaviour". So no, it's not something that only happens to me.
I guess it's one of those things that are backdoors disguised as features like UPnP and SSH.

Thanks for the reply.
