    Hi all,

    So I heard if I upgrade my cable modem (using old old linksys) that I cold get faster speeds.. I bought a motorola SB6120 DOCSIS 3.0 because they just approved it on COX. But my speeds stayed at about 4.5mb, when I should have 12.

    I traced it down to the BEFVP41 I have at the house. If I connected my computer to the modem directly, I'd get almost 20mb.

    I use the VPN router for a tunnel to the office with a BEFSX41 at the other end. It works great, but I want the speed I'm paying for. The BEFVP41 was old and I figured i'd just buy a newer router. I search around and got the RVS4000. Of course after searching and reading here I see it was probably a mistake.

    I set up the RVS4000 and see the throughput is better. I'm getting 17mbit now, and thats through the router and two switches.

    The problem is I cant get the damn tunnel to connect. The problem is a combination of fact that I'm using a dynamic dns service to get to the office, and the VPN router at the office is behind another router. So the WAN side of the VPN router has a local IP and does not match the IP of the dynamic DNS domain.

    So I assume this "feature" (matching IP of router with domain) adds security but all it does is add to my headache...and expense. All I wanted was to get the speed I was paying for!!! now I've spent almost $250 and I'm worse off than I started.

    Is there any way around this with this equipment? I dont see any place to tell the RVS4000 to ignore that IP address and just connect like the old router used to. I cant get rid of the router in front of the VPN router at the office because the subnet in front of it is semi-public, and I dont want them to have access to the lan side of the VPN router.

    If not, is there any router I can buy that will connect to the BEFSX41 or BEFVP41? I only have 3mb service at the office so I dont care if I use the "slow" BEFVP41 there. What I'm trying to avoid is having to buy *two* new routers because at that point I might as well return everything including the cable modem and save my money.. it's just not worth it.

    I'm sure there are other cheaper Linksys routers that will connect with an SX41, but I know that the RV082 will because I've done it and the cheaper RV042 should be able to do it too. Unfortunately if you buy either of those, you would be paying for a second WAN that you wouldn't be using, but you would be buying a reliable router.

    The RV082 is the stablest router I've ever used. Mine has only rebooted once in three years and that was when its uptime counter hit something over a year and a half of uptime. I think the uptime counter cuased the reboot.

    There are some set up configurations listed here for the RV082 and VP41 under gateway to gateway: http://www.linksysinfo.co.uk/routerworld/

    Thanks for the info. I went out and bought a RV042 and unfortunately I have exactly the same problem. The RV042 is trying to verify the other endpoint is reporting the right IP and because the endpoint is sitting behind another router, I can't get it to accept the connection because it's IP isn't the same as the pubic IP.

    <sigh> How much more do I have to spend.. :(

    You must have the router at the office as the first router or else set it on a DMZ port. DMZing a hole in the other router may not work though.

    The dynamic connection is solvable with the authentication of an email address or an FQDN.

    I cant have the VPN as the first router as that would open the LAN side of the VPN router up to office visitors. I'm trying to keep the visitors off the corporate network and just let them share the internet connection.... and the VPN is already DMZed through the first router.

    If I put the RV042 at the office and the old one at the house, that may work, but then I'm again using an old router which probably has low throughput like the other one and defeats the purpose of doing anything in the first place.

    The RV042 does support NAT-T which seems like the option I need, but according to the help on the router, it would appear the only way this is going to work is if both routers support this.

    At this point it seems my only other option is to use the old routers and live with my slow internet, or buy another RV042.

    Thanks again for your help.

    Does the office have true static IPs or are they dynamic?

    The office and the house have dynamic IPs. I use dyndns service at the office to maintain a domain.

    I looked into that, but just getting even one static IP raises my DSL bill by almost 50%.. but that would be the simple way to do it..
