    Hi everybody!

    For a while now, I've been struggling with trying to connect two remote networks using VPN and hopefully someone will be able to help me.

    First network –,

    Second network –,

    First network is using a gateway that is configured under Windows 2008 server r2 foundation. This gateway has two network interfaces one is local (and it’s up is and the second one faces the internet and configured with static ip and NAT

    Second network is behind the router Linksys RV082 which also has a static ip.
    I’m located behind the first network. I installed QuickVPN on the server, added the required certificate and I’m getting errors when I’m trying to connect. Here are the logs that I got from QuickVPN :

    Firewall is configured correctly.

    I am able to connect to the Network 1 with QuickVPN using the static ip without any problems

    My theory is that this problem is somehow related to NAT and that QuickVPN is somehow not configuring IPSec tunnel correctly but I cannot pinpoint the issue.

    Any help would be greatly appreciated.

    quickvpn needs remote management enabled, and that your own PC quickVPN is on does not block ICMP request (ping) some Antivirus/firewall programs also block this.

    Windows 7 and Vista need the firewall enabled since this is linked to IPSec.

    Thank you for your fast response.
    Nothing is blocking icmp and there is no antivirus installed. I double checked to make sure that firewall is configured correctly.
    I think its not connecting because of the gateway configuration. With the same internet configurations, same external ip as the gateway's, connection on windows 7 could be established with no problems.
    How would you configure the tunnel in my case?
    Thank you, I really appreciate your help.
