    Which is the better router?

    I'm looking into getting two routers for a site to site vpn (preferably using hostnames rather than ip addresses). I'm also something of a feature junkie - I'd much rather have more options rather than less. Being able to support roaming vpn clients isn't necessary, but would be handy with a laptop at some time. Finally, one annoyance I've had with my current router is that I could never get wake on lan to work (I can't forward ports to a broadcast address).

    The vpn would handle some network browsing, but I would like to backup certain files across it, so I would like some decent speed. I currently have an Asus SL1000 and SL500 at the two sites, but I've found that the Asus isn't quite up to it. It actually does work, but it appears to be ram restricted. (The device only has 16MB of ram - the vpn works fine if I turn off enough services on both ends, but with the normal amount of services the vpn isn't stable. UPnP seems to be a problem in particular.) The routing speed of the Asus is excellent however.

    In looking over the Linksys routers, it looks like the two I'm most interested in is the RV082 and the RVS4000 (and the RV0042 - but it looks like the RV0042 is practically unavailable). I'm not considering the RV042 simply because I'm worried about reaching hardware limits like I have with my Asus routers. From what I've gathered the RV042 has already lost some features due to it's smaller flash size (in comparison to the rest of the family). The RV016 has a nice bump in ram, but I think the price is too much to justify the extra ram. I don't need the extra ports so that would be wasted. Of course, the down side is that it's only a 10/100 switch on the inside. (Which isn't a huge problem - I'll likely end up getting a gigabit switch to connect to the inside.) Another potential downside is that it looks like the RVS4000 may be the RVxxx replacement - so I'm afraid that bug fixes may eventually be stopped as Linksys puts more resources behind their new router.

    I can't find the specs of the RVS4000, but the fact that it's so much cheaper makes me think that it's likely on the low end (around the RV042 levels) which makes me concerned about how capable it really is. I really don't need the dual wan capability of the RVxxx series so that isn't a problem with the RVS.

    I've contacted Linksys directly, but naturally they don't want to make a commitment - all I could get from the tech was that either one should work.

    Has anyone used both routers and has a preference?

    Thanks for your help!

    Feature-wise RV042 is very similar to RV082, except for VLAN and VPN Backup. If you need decent VPN throughput, you need RV042 or RV082. RVS4000 has IPS and better VLAN support than RV0xx.

    RVS4000 also includes an intrusion detection engine -- which comes with one year paid up support. After that you must buy pattern updates for the IDS engine.

    From the Linksys datasheet for the RVS4000...

    "IDS/IPS network intrution detection and protection services with email alerts
    - Free signature updates are provided for one year"

    Thus the RVS-4000 may have a lower entry cost - but the total cost of ownership may equal over time -- it all depends on what you really need.

    This isn't necessarily bad - the point is that the RV-0xx and the RVS4000 appliances are for somewhat different markets/customers. With the RVS4000 you will want to plan on buying the update service in the future -- otherwise the intrusion patterns would become stale and provide you less protection, i.e. less value. Of course the RV-016/042/082 do not provide the IDS engine so that is one less feature in them -- but the RV-042/082 dors include WAN load balancing / or WAN failover.

    RVS-4000 also has a faster VPN engine and that may make a difference if you are using it for VOIP

    I doubt that very much. The RV042/82/16 uses Hardware VPN. The 42 can handle 50 VPN Tunnels. The RVS400 handles what 10 at the most? the RV082/16 handle 100 VPN Tunnels. I know for a fact the WRVS4400N uses a software approach to VPN Tunnels, and I would assume the VPN tunnel is of a similar nature to that of the WRVS4400N.

    As the saying goes, you only get what you may for:) I didn't need Dual WAN, but the RV042 is a solid performer. the RV0xx series does handle Bandwidth management on protocols and has priority over ports.

    Quite right... late night and I saw the NAT speed which is 800Mbs, not the vpn speed. The data sheet doesn't say which processor is used... I would presume that they stuck with the Intel Network processors though... but they could have used a slower processor.

    The gigabit features are (I believe) mostly just an evolution of the chipsets. Not many switch chip makers are designing chipsets for 10/100 anymore.

    my guess is the RVS4000 wont be an intel chipset. look at the price:)

    Thanks for the help everyone.

    It looks like the RVxxx is the best choice for me. I think I'll go with the RV082 as opposed to the RV042 - but it looks like either should work.

    Ironically, I selected the Asus SL1000 over the RV082 a few years ago (at the time the Asus seemed to have much better Nat throughput and VPN was a bonus, not one of the main considerations). Strange that the better routers still seem to be from a few years back.
