My first experience with DD-WRT is with a Linksys WRT54GL router. The install and configuration went fine and I am running the OpenVPN firmware. My VPN (and Usenet) provider supplied a startup script to configure the VPN connection as the recommended firmware version for this router (dd-wrt.v24-12548_NEWD_openvpn.bin) provides very limited configuration tools for the VPN.
I installed the script, rebooted the router and successfully connected to the VPN tunnel. However, when I accessed the Usenet server I found that my download speed was about 25 - 30% of what I achieve without using the VPN. I also noticed that the router CPU was pegged at 100%. If I navigated the router's web interface I observed that the NNTP traffic speed dropped noticeably. CPU usage stayed at 100%. It is my conclusion that I am limited by CPU power since navigation the web interface stole some CUP cycles and further impeded the VPN traffic.
Bottom line - I think I need to procure a more powerful router. Am I correct in my thinking? Any recommendations?
You are quite correct. Encrypting the large amount of NNTP traffic seems to be overwhelming the poor little processor in the WRT54GL. I looked at the routers which you recommended. $$$ Ouch! I really do not need to tunnel the NNTP traffic through the VPN as I am connecting to port 443 on the Usenet server and encrypting the traffic on the PC using stunnel.
I think I may connect the DD-WRT router and the dedicated NNTP download PC to my old Netgear router. I can then tunnel all other traffic from my other PCs through the VPN and let the NNTP traffic bypass the VPN.
Or I might install the VPN on just a couple of my PCs with which I am most concerned and allow the NNTP PC free access.
Or I might setup a little micro-PC as a Linux gateway to the VPN
Or I might purchase a high $ server (I have seen some in the price range of the two models you list which are already installed with DD-WRT ready to go)
Or... see what other responses I get to my question
A static route sounds like what I need. I see the option to create on under Setup; Advance Networking. However, I have no idea how to configure this. I can guess that the Destination LAN NET would be the Usenet server. How do I point only NNTP traffic to this destination? Or am I off base - do I need to setup the static route on the Usenet download PC?
I am sorry if I have been unclear. I am not running the Usenet server. I am just a leacher . I have a Dell Inspiron Micro PC (which only draws about 5 watts) which I use for Usenet and other large downloads - Linux ISO files etc. - rather than my regular desktop which draws a 150 + watts. I have 4 other PCs on my home network.
As I cannot run downloads at a decent speed through my underpowered DD-WRT router when using the VPN, I would like to connect the micro PC directly to the Internet (or just the Usenet server) bypassing the VPN. All other PCs would connect through the VPN.
I have managed to connect the old Netgear (non DD-WRT, non VPN) router to the Internet and then connect the Linksys uplink port to a regular port on the Netgear. I then can connect my network to the Linksys. This allows my network to connect through the VPN.
I next connected the micro PC to the Netgear. This allows the micro PC to connect directly to the Internet without the VPN. The problem I have with this configuration is that I normally run the micro PC headless and connect to it with x11vnc or vncserver remote access. I currently cannot reach the micro PC from other PCs on my network as I have not yet managed to get the proper configuration to communicate from the 192.168.0.x LAN back to the micro which is on 192.168.1.x - the network of the Netgear router. I have played with static routing but so far without success.
What are your speeds with and without the VPN? The routers previously suggested are expensive, but you can get something considerably more powerful than your 54gl for <$50. It won't match the high end devices, but if you're getting 25-30% with your current setup, I suspect those high end devices are overkill. I'm not especially familiar with broadcom routers, but for Atheros, the tl-wr1043nd v2 comes to mind. It has a 720mhz processor and 64mb ram. I setup an Archer c7 v2 for a friend, which has the same processor, but 128mb ram, and he regularly streams Netflix in HD over his VPN. The c7 is ~$100, which is why I suggested the 1043. I have both and love them.
