Configuring DD-WRT on the Linksys WRT1900ACS for Multiple WiFi SSID and VPN Setup

VPN Overview

My point is this. Before going gung-ho and installing the DD-WRT firmware, I recommend you setup the router and test its basic functionality first. Put something needlessly long and complicated here! The basic wireless settings give you two default interfaces, ath0 5Ghz and ath1 2. This section discusses the main architectures for PPVPNs, one where the PE disambiguates duplicate addresses in a single routing instance, and the other, virtual router, in which the PE contains a virtual router instance per VPN. I just installed dd-wrt on my ac linksys router. Thanks for taking the time:

The Built-in Media Reader can directly import photos from compact Flash devices, SD cards and memory sticks without the need of a computer. Memory capacity options are GB or 1TB, with an extra empty bay. The Media Hub's GUI gives a holistic view of the media located on the network regardless of where the actual file is located. Albums are consolidated, artwork, track numbers, and other metadata are downloaded, and all information can be sorted by a variety of different criteria.

Full 20 Mhz Wireless Channel: Physical Interface ath1 2. If you are connected using wireless and not Ethernet, you will get disconnected. Just reconnect using the new SSID. Wireless Security For each of the wireless interfaces ath0 and ath1 configure your wireless security. The configuration below may differ depending on your preferences.

Wireless Security ath0 Security Mode: Put something needlessly long and complicated here! Wireless Security ath1 Security Mode: Now for the exciting part. You can choose whether the virtual interface will use ath0 5Ghz or ath1 2. Our first step is to create a bridge. This is optional, just my preference to use a small DHCP scope.

Set the DHCP range to start at. Obtain this from your VPN provider Port: Obtain this from your VPN provider Password: Additional Config persist-key persist-tun tls-client remote-cert-tls server. By following this guide carefully, you should now be able to connect your devices to the new wireless network SSID and will be using your preferred VPN provider. I have intentionally not recommended a VPN provider in this article since a Google search will yield many results. There are other guides out there that talk about similar configurations, but I found some of them to be out of date or just too damn complicated.

So, I would not recommend using custom WRT to anyone anymore, if the contracted speed is more than Mbps. From Mbps the routers all 5 routers I had in the past 10 years behaved in the same way became unstable and hitting the limit at Mbps could came with a crash.

What CPU specification did those routers have? My point is this. While these tests are unverified, it is not possible to put a limit like Mbps without taking the hardware specification into consideration. I wanted to raise a bit the awareness about this fact. Some of your readers might try it and might be disappointed, even without knowing why: Thanks a lot for the guide.

I just installed dd-wrt on my ac linksys router. Hi, I used similar instructions on my linksys wrtacs running dd-wrt. It has preformed well, I have experienced quite a loss in download speeds but have maintained consistent upload speeds. However, I own a HDHomerun connect, connected to my router via the lan port and I have been unable to get it to work.

Would you have any idea what settings may be preventing this device to work? I plan on contacting SiliconDust support but was reading this article and thought you may have more insight being familiar with dd-wrt.

In the past, companies would have rented expensive systems of leased lines to build their VPN only they could use. A VPN provides the same capabilities at a much lower cost. In effect, private data, being encrypted at the sending end and decrypted at the receiving end, is sent through a "tunnel" that cannot be "entered" by any other data. IPSec Internet Protocol Security provides security services at the IP layer by enabling a system to select required security protocols, determine the algorithm s to use for the service s , and put in place any cryptographic keys required to provide the requested services.

IPSec has been selected to be embedded in IPv6. Today IPSec is the most secure way to access the corporate network from the Internet, here are some elements why: Protection against denial of service attacks.

The IPSec protocols use a sliding window. Packets are numbered and only accepted if they fit the window. A NAT device takes a packet"s originating private IP address, translates that address into a public IP address, before sending the packet across the Internet to its destination.

NAT devices use an internal table to keep track of translated addresses but unfortunately manipulate the packet"s original IP header, impacting IPSec ability to function. NAT Traversal is now widely implemented in routers and appliances. The differences between Transport mode and Tunnel mode can be defined www. Computer authentication by IPSec is performed by using preshared keys or computer certificates. A pre-shared key identifies one party during Authentication Phase.

Per definition, "Pre-shared" means you have to share it with another party before you can establish a secure VPN tunnel. The strongest method of authentication is the use of a PKI and certificates. However, smaller organizations cannot afford the implementation of a PKI system and a well managed preshared key method can be easier and just as powerful. This mechanism is used by the Redundant Gateway feature.

A new checkbox appeared in VPN Client release 5. Releases which support old Windows versions: English, French, German, Portuguese, Spanish , Check our supported languages list , increasing daily, to find your language. The language can be selected during software installation of the VPN Client. The localization process is very simple and the translation in your language will be available on our next release.

If the equipment you are looking for is not contained in this list, please contact our tech support and we will work with you to certify it. We will need configuration file, log file from "Console" window and a screenshot of the router configuration page.

We've made available for download VPN Configuration Guides for most of the gateways we support on our web site support section , and there are some on Linksys. VPN Configuration Guides are either written by our partners or by our engineering team. We've made available for download VPN Configuration Guides for most of the gateways we support on our web site, and there are some on Cisco. However, there is a workaround. Linksys has released a newer firmware since then. You might want to test it: See also other FAQs: With most of VPN gateways, this address must not belong to the remote network subnet.

For example, if you use a VPN gateway with a subnet Take the case you choose an IP address non-used in the subnet like But, this request cannot receive any answer because the client is not physically present inside the subnet. So, initial packets from the client will not be answered. It is possible to run the standard VPN Client setup in "silent" mode. You need to download the whole procedure described is this document: Redundant Gateway can offer to remote users a highly reliable secure connection to the corporate network.

Remote gateway failure is detected by "Dead Peer Detection" function. A specific IKE Port can be set. When I try to activate the software, it doesn't succeed I got an error message. You can find a complete help guide about the activation on our Online Software Activation Help Guide. You can also get your software activated at anytime, by following the procedure described on our Manual Software activation. It enables to establish a secure connection to TheGreenBow remote gateway and demo server.

Yes, license can last several weeks. For further details, contact our sales team. In the Script window, you can select the application you want to start before or after a tunnel opens or closes. TheGreenBow supports several two-factor and two-way authentication Tokens to store users, personal credentials, such as private keys, passwords and digital certificates. Please see the Certified Token List. In some hotels, hotspots or airports, the UDP port and for outgoing traffic might be prohibited, preventing any outgoing VPN Connections to your corporate network.

If you decide to use non default VPN Ports i. Here is the diagram for example above, knowing that some router models do not provide the capability to reroute ports within itself and two routers might be needed:
