RV042 port forwarding

    I have two RV042's connected by VPN tunnel supporting two Nortel BCM telephone systems. Everything works great until we set up port forwarding for some external services. As soon as a port is forwarded we loose audio through the tunnel even though the VPN is still set-up and working.

    This is version I saw a thread that said that was a better version but before we go there, i am wondering if anyone has any ideas as to how to fix this problem.

    The ports that we are forwarding are 3389, 80, and 443. I suspected ports 80 and 443 so we just set up port 3389 but the problem exists with only 3389 forwarded.

    Linksys support was very helpful - we don't support voice over VPN on our routers. Gee thanks for the effort!!

    You may be in for a lot of headaches with the combo, the RV042 isn't the most powerful of the VPN servers and it lacks the QoS features that you really need for voice/video. I doubt changing firmware will make much difference. Sounds to me like you really needed a RVS4000. Sorry not much help...

    as crummy as it may sound, I had voip issues with quality on my rv042 as well. I ended up with the rvl200 and so far so good. the downer is only 1 ipsec tunnel. I cannot speak for the rvs4000 but my situation improved greatly with the qos and the ssl vpn is cool.

    I believe the RVS4000 supports up to 5 vpn tunnels. Plus the faster thru-put, QoS, and built in support for intrustion detection. I have RV082's and RV042's and can see the writing on the wall... Just a couple of more years and both those products will be replaced. :eek:

    I believe the problem SEARAY is having started when he added the port forwarding to other external services. That takes CPU cycles from the RV042 but also the extra traffic is handled at the same priority as the voip. You really want to rate the VOIP higher and the extra services lower. In the RV082 you can make some adjustments in the WAN BANDWIDTH tab that might help... but still not the QoS settings that you have on the RVS4000

    Of course this means spending more money to fix the problem... :mad:

    try using the hidden port QoS in your routers configuration to set the port to High which is being used by the Nortel VOIP.

    when you login to the router webgui add hidden page to the URL

    Have not had much luck with that item really working. Last I read it was indicated this was hidden and not used as it was a left over from the RV082... I tried this on my RV042 and it made no difference for me.

    Thanks for the tip on the hidden menu item - I tried it and made the port that had the BCM connected to it "high" but it did not fix the problem.
