TomatoUSB

I'm using Tomato Firmware v1.28.9054 MIPSR2-beta K26 USB Ext

Recently I've been getting odd redirects at one of the sites I visit on my anroid tablet at home to a porn ad site. I've looked for malware on my tablet but haven't found anything, it would surprise me if I had any malware on it. Instead I decided to try to block the site. I looked up how to block a specific IP using tomato, or any linux run system, and came across the use of iptables. I looked up the IP address of the site using an online IP lookup site and used the following command in the firewall scripts section of tomato:

iptables -I wanin -s 173.244.199.130 -j DROP

I rebooted. But when I type in the URL in my web browser I'm still able to access the site. I've tried adding the address to all the different ip table chains and tried different domains/ips but nothing seems to work.

Am I missing something obvious? I probably am as I'm rather new.

Thanks!

Try this in the firewall. Reboot.

iptables -I FORWARD -d 173.244.199.130 -j DROP

You should check the order of rules with "iptables -nvL" from console or using tools-command. The specific rule you quote would only block new requests from that site, but the iptables packet filter 'firewall' will let it reply to web requests under the 'ACCEPT RELATED/ESTABLISHED' FORWARD rule. So wanout with that site as a destination should work.

You should also be able to use the web gui access restrictions which will insert a rule in correct place.

Does your tablet/browser have a provider caching system? My kindle has this, the Silk browser will pull a cached copy of a web page from Amazon's servers before pulling it indirectly from the site. If you want to turn it off, turn off accelerated page loading from settings from the menu in Silk.
