TL;DR Version:

So I installed the latest DD-WRT and it seems I'm unable to visit the following websites:

www.stumbleupon.com

https://myaccount.safelite.com

However, if I plug my computer directly into my cable modem or if I launch a VPN (I'm using Private Internet Access), I'm able to get to both sites fine. And fyi, I don't live in a country that filters Internet traffic, I'm in the US!

Long Version:

My router is a Linksys N300.
FCC ID: Q87-E1200V2

I've installed DD-WRT using these instructions:

https://www.dd-wrt.com/wiki/index.php/Linksys_E1200v2

Except I downloaded and installed r33555 from here: https://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2017/10-20-2017-r33555/ (I basically used the r33555 versions of the two firmwares I was instructed to download in the instructions.)

And as far I as I can remember, I'm using the default settings, except for the following:

- WPK2 Personal with AES
- Wifi mode: NG (I have 1 device that only supports G.)
- Extension Channel: Upper

And I found that there are some websites I'm unable to connect to at all, but I can connect to them fine if I use a VPN or connect directly to my cable modem.

Stuff I've tried so far (with no success):

- Disabling the SPI Firewall
- Playing around with the Access Restrictions (there are NONE to begin with so I'm not sure why it's blocking websites to begin with.)
- Connecting to the router directly with an Ethernet cable
- Visiting the two "blocked" websites on other devices using the same router

How do I begin to resolve this?

See if it is a DNS problem, go to http://whatismyipaddress.com/hostname-ip

and search for the IP address of the websites you can not visit and type in that IP address in your browser. If you can connect you have a DNS problem

N.B. If using VPN and policy based routing disable SFE

ssh into your dd-wrt router and run:

nslookup www.stumbleupon.com

curl www.stumbleupon.com


what output do you get?

DD-WRT does not censor the web unless you instruct it to do that. So it might be due to your DNS servers.

Use e.g.

208.67.222.222
208.67.220.220
208.67.220.222

are you using privoxy? Its hardcoded list has some domains blocked, for example, every domain that ends with .ru or .tr (I even thought of making a post requesting to leave politics out of DD-WRT, but gave up...)

I enabled sshd to allow me to SSH in and had to restart my router in the process, but after the restart, it looks like I'm able to access both www.stumbleupon.com and myaccount.safelite.com with no issues anymore.

So weird...

Edit: Issue hasn't come back as of now so I'm marking it as solved.
