Dd wrt access restrictions
Dd-wrt – basic configuration
Hi everybody – In accordance with the subject. What is the mechanism behind this? I’ve set up a schedule for a particular mac address, but if the client has an established session to a webpage, they can continue to use it – it doesn’t “throw” them off the network. If they reset, everything goes back to normal. Is there a way to delete them from the network instantly using a cron script or other means such as arp spoofing? Thank you. Netgear r7000, Freshtomato 20.3.

On dd-wrt, there’s a similar issue with Access Limitations. And the trigger is the ESTABLISHED/RELATED firewall rule (FORWARD chain), which often comes before the Access Restrictions firewall rule (iirc, the lan2wan user-defined chain in dd-wrt). It’s essentially a structural error. I’m not sure if tomato has the same flaw (I’m not sure because I never use it). However, your explanation of the problem sounds suspiciously like dd-wrt. To fix the issue, I advised people to uninstall the lan2wan rule and reapply (insert) it to drive it ahead of the ESTABLISHED/RELATED rule.
Dd-wrt: fixing port forwarding in newer releases
Let’s get this out of the way: we’re just interested in blocking Internet pages at particular times of the day. (Throttling use would be even better, but quality software on that front appears to be lacking.) The first step is to admit that you have a problem. Step 2 is to collaborate with someone else to come up with a plan that everyone will agree on. In this situation, slowing things down could be beneficial.
When I first started looking into this, I was ecstatic to find that DD-WRT already had a “Access Restrictions” control called “WAN Access.” All of their documentation explains precisely what I was attempting to do. The only issue is that it does not work! My preferences are listed below:
Also, double-check that the MAC addresses correspond to the computer’s relevant interfaces. On Windows, use the command ipconfig, and on Unix-like systems (such as GNU/Linux or FreeBSD), use the command ifconfig.
Networking – setting up internet access restrictions
Many organizations that implement a big ERP system have large networks that are operated centrally from a single location, which is often in another country. The network engineers are usually obscured by layers of helpdesk workers and are only reachable through bureaucratic online forms if at all. Outbound connections may be over-protected as a result of these factors, making an internet connection useless for productivity protocols like Microsoft Outlook (IMAP over SSL, SMTP over TLS) and Terminal Services Client (RDP). Using DD-WRT to catch packets and transfer them via an SSL link is a quick way to get around a poorly designed firewall and conceal network traffic from a nosy network engineer.
DD-WRT is a very appealing firmware for home and small business because of its comprehensive feature set and low price. It’s simple to set up on most supported routers and gives a $50 router the functionality of a $800 router.
Many of the features that were once only available after flashing a router with DD-WRT are now standard in the router manufacturer’s proprietary firmware in recent models, but there are still some gold nuggets that can only be found after flashing a router with DD-WRT. The SSH shell and the ability to route IP traffic through it is one of those functions, making it a very powerful and stable proxy server. This proxy server allows a user to connect to the internet from his home instead of the office network. This proxy service is only possible thanks to a strong SSH client and DD-WRT.
How to block a device in dd wrt router
You may use Access Restrictions to establish a set of rules that control internet access for your network’s machines. You may build rules that restrict access based on an individual’s IP or MAC address, an IP address range, the time of day, the type of traffic, the URL and keywords used, and so on.
Each collection of rules is referred to as a regulation, and you can build up to ten of them. A policy may include several individual rules, such as filtering access to a specific web site by a specific machine and/or filtering access to certain unauthorized P2P protocols by a specific machine.
Filter allows you to restrict links to specific websites, programs, or keywords. However, unlike the “Deny” alternative, it does not fully block internet access. It also doesn’t allow access to the internet while a Deny policy is in place.
Click the Overview button to see a summary of all the policies. Every policy’s number, Policy Name, Days, and Time of Day will be shown on the Internet Policy Summary screen. To delete a policy, first check the box next to it, then press the Delete button. To return to the Filters screen, click the Close button.
