    I need to get 2 sites connected via VPN.
    Both sites are connected to the Internet via ADSL and PPPoE.

    My idea is to use two dyndns Domains and build up a IPSec VPN connection using two RV042s.
    A third site is planned to get connected later.
    Only Linux machines are used on both sites and need to communicate during the day permanentely.
    No Voice or multimedia traffic but stable function is really required.

    Has anybody running this combination stable?
    Something special on this?
    Maybe one RV082 is helpful in this combination because of a third site is planned for the future?

    Thanks :)

    Define stable? Its seems to work for the most part from what others have come across but it also seems to go down more then ipsec using ip as an identifier vice fqdn.

    Will you be trying to use both WANs on each RV042 with ADSL and PPPoE? I read some reports of the router having problems if the dynamic IPs issued to the WANs on a router are in the same /24 subnet. Can't say if these problems are true or not.

    I've avoided the possibility of that situation occuring with my RV082 though when I obtained a second PPPoE ADSL line just in case it is true.

    Depends on what you need for uptime. With Dyndns on each'll naturally experience some downtime until the client updates dyndns's servers and the other end realizes the update. Logic dictates it's not as solid as having statics on each end. If you NEED more reliability, spend the money and upgrade each end to static. I've done a few dyndns tunnels, and naturally there's expected lag until things update..there's not as much under your control.

    Thanks for all the answers :)

    I planned to only use one of the WAN Ports and of course I'm aware of the natural DYNDNS restrictions.

    I just hoped to hear something more specific about the RV042 / RV082 devices reliability and issues / needed workarounds etc. but now with a new fiemware out everything can change again anyway...

    vpn connection between static and dynamic for more than 24 hours

    Hello People

    I have been trying for the past two months, asking the whole world how to maintain the vpn connection between a static ADSL RV016 and dynamic ADSL RV042 for more than 24 hours.

    Yes, no matter what combo config I use, it will collapse after 24 hours.

    So any kind souls out there, pls lift me out of this torment.

    1. Has anyone maintain his/her vpn between a static and dynamic ADSL for MORE than 24 hours, or preferably as long as possible??

    If yes, pls help out with some screen shots.

    2. Or rather, does the vpn connection above does not actually last MORE than 24 hours? Is it inherently only last a maximum of 24 hours?? Becos I assume that it can last more than 24 hours.

    I figured that the last resort is to request the end user to click the "Connect" button before they start work every morning. I can;t do it for them forever...

    RV042-1 set local IP, remote to FDQN

    RV042-2 set local FDQN, Remote IP with resolv from dynamic dns

    Try these (my settings with two WRV200):

    - on the static site use "any" in the "remote securitiy gateway" setting

    - on the dynamic site type in your static ip

    I do not know, if it is secure enough, but it is the only way to solve this problem, i think ...
