RV082 Dual Wan and Port Forwarding

    Heyo,

    I was wondering if anyone can duplicate the following situation. We recently bought an RV082 and tried putting it on our network. Shortly there after we realized our network wasn't port forwarding. After some testing we figured out that our unit, when put in Dual Wan mode, or more acurately enabling both WAN's at once caused port forwarding to completely fail.

    Our Test scenario:
    Reset the router to default.
    Setup WAN1 (adsl)
    Setup port Forwarding (8 0 to 192.168.1.12)
    Test from branch office --> Success
    Setup WAN2 (sdsl device)
    Verify forwarding still instact
    Activate WAN2
    Test from branch office --> Failure

    This test was repeated doing WAN2 first as well and the results were the same. When 1 connection is enabled port forwarding appears to work correctly, when both are enabled port forwarding fails.

    Can anyone else verify these results? We would really like to know if our product is defective, or if this is a failure of the firmware.

    Gizmo.

    Hmm is it only port forwarding that goes down?

    As far as we can tell yes. Internal redirection seems to work fine, vpn tunnels still behave correctly, however inbound port forwarding seems to be disabled.

    Hi

    I have just purchased an RV016 and am experiencing a similar problem.
    I have discovered, that when a remote ip connects to say port 110 on WAN1, and then does another connection to WAN2 (of any port), WAN2 will deny it access. (Done with 2 cable lines with diff IPs and gateways)
    I guess this is because the routing table doesn't work on a per connection basis, and uses a per IP basis for deciding which WAN port to send data down.
    This is causing a great problem for me, i can't fix it, and if no solution comes up, it will have to be returned.
    I bought it to replace a dual WAN Hotbrick VPN 600/2, which although works absolutely brilliantly, only has 2 WAN ports and I want more :)

    Latest firmware used, all sorts of options on access rules tried, help?

    Regards
    Jonathan

    EDIT: Used the live chat thing, didn't really help, and here is the convo:

    Soledad Sayo: Welcome to Linksys Live Tech Support. How can I help you today?
    Jonathan: good morning, did you see the above long message?
    Soledad Sayo: good morning too..yes
    Jonathan: (morning in the UK anyway, 10:30am)
    Soledad Sayo: So basically you were able to use the wan port one at a time right?
    Jonathan: well, both can be used, but not at the same time by the same ip address on the internet
    Jonathan: eg, 1.1.1.1 can't connect to wan1 on port 80 and wan2 on port 110
    Jonathan: the latter connection to port 110 fails because the router sends back data on wan1
    Soledad Sayo: yes jonathan because you cant use both connection at the same time
    Soledad Sayo: it is only for back up connection
    Jonathan: that seems rather odd to me
    Soledad Sayo: so basically when the 1st connection disconnects, the 2nd connection will activate
    Jonathan: it load balances perfectly for computers on the LAN
    Jonathan: so with 2 1mbps lines, i can download from 2 places at 1mbps each
    Jonathan: but when i host servers behind it and port forward, remote clients can only connect to 1 wan at a time
    Soledad Sayo: because the load balancing of the router is only for the back up of the connection
    Jonathan: then why does the linksys website say it can load balance on http://www.linksys.com/products/product.asp?grid=34&scid=29&prid=624
    Soledad Sayo: One moment please...
    Jonathan: ok, i'm at work, so if i take a while to reply (wouldn't be long), you'll know why :)
    Soledad Sayo: One moment please...
    Soledad Sayo: have you tried setting the upstream and downstream settings for the traffic?
    Jonathan: yes
    Soledad Sayo: but still it is the same thing
    Jonathan: yes
    Soledad Sayo: ok,
    Soledad Sayo: jonathan can you please send us an email regarding this particular problem that you are experiencing with the router and send it to support@linksys.com so that we could forward this concern to product development so that they would be able to run some test regarding this matter
    Jonathan: how long is this likely to take, since i'm perfectly willing to have a better model shipped to me and i'll pay the difference
    Soledad Sayo: If you will send us now an email we can forward your email to our development and they will run some test regarding this matter and hopefully will email you a resolution regarding this matter.
    Jonathan: any idea on how long it will take them though?
    Soledad Sayo: Usually it takes 3 days to 1 week to test. But if you will not be receiving any resolution, it is with your discretion to try another brand. Sorry for the inconvenience Jonathan
    Jonathan: this is the first time i've had a problem with cisco/linksys too :(
    Soledad Sayo: I really apologize for the inconvenience this has caused you Jonathan
    Soledad Sayo: But at this moment that will be the best advise or suggestion that I can give you.
    Jonathan: ok, i'll have a think, thanks for your time, bye
    Soledad Sayo: Thanks too Jonathan for understanding

    That live support thing sounds about as helpful as mine was. Only mine didn't tell me to email support, just return the product.

    At the moment I'm seriously wondering what the point of offering a 400$ vpn device on the market is if it doesn't actually do any of the dual wan features its being advertised with. What's more confusing is if it's a linux based product why they don't just robust the portforwarding and dual wan out a bit as far as configuration is concerned and remove the load balancing (who cares about going out, it's about what's comming in anyways.)

    this is old, but nonetheless worth a response. I have a RV082 and I was having same problems as you, and what I did as a workaround was to use the protocol binding feature. This fixed the problem for me as it did what I intend to do, that was to only foward the service I want in the port I needed.

    We had multiple problems with this sort of thing on our RV042; the only workable solution which I found was to bind protocols to a particular WAN and particular IP when possible. Not what I wanted, but with enough planning on what protocols go out what WANs (we have a WiMAX and a DSL connection, so the performance and latency is different) and we've still seen an over-all performance increase over using just one connection.
