QuickVPN to WRV54G from behind RRAS

    I have a WRV54G at home, and want to QuickVPN to it from the office. At the office I am running Windows Small Business Server 2003 which uses RRAS to provide NAT/Firewall/Router functions. I don't think RRAS is blocking any outgoiong ports, although I am not quite certain were to look for that. I try to QuickVPN both from the server itself, and from an XP client sitting on the inside network, and I keep getting "The remote gateway is not responding". If I disable Windows firewall on the XP machine, and hop on someone's wireless network in the next office, I can connect ok. So I guess I am asking is anyone is successful in QuickVPNing from behind a non-Linksys firewall. And by the way, why do we have to turn off Windows Firewall??

    Yep,

    I conncect from behind different routers at hotspots and hotels all the time with quickvpn. The issue with the windows firewall is that it is "overly" restrictive to the point even "good" packets can be denied access. When quickvpn gives you "verifiying network," it's negotiating the ip security portion. Because windows firewall is blocking the packet from the router (it thinks it's an invalid icmp packet) the router finally gives up and drops the connection.

    It's best to use a third party firewall such as zonealarm or norton internet security (2002, 2003, or 2004) because you can keep your firewall up and still use quickvpn. The only time I ever have to drop my firewall is when I'm at a hotspot (most likely due to the firewally rules on their router).

    Thanks Doc. So what can I do about Microsft RRAS? It is a firewall that I can filter and use to restrict ports. Shouldn't a client inside RRAS be able to get through using QVPN? I can't find anything in RRAS that would be restricting it.

    Could you explain that a little bit more for me, please?

    RRAS has the capability to allow you to filter and disable certain ports during setup if I'm not mistaken. Depending on the setup, either the particular packets utilized by quickvpn are being filtered out by the office network, or there's a configuration issue somewhere along the line.

    I am in an executive suite, I have a dedicated pipe to the internet from my office. I run Windows Small Business Server which installs RRAS as a router and firewall. I am not terribly familiar with RRAS, I know how to open incoming ports, but I dont see any specific outgoing ports being blocked. Maybe I don't know where to look. In any event, a client computer on the inside of the SBS server cannot QVPN. As a test, I hopped on the shared wireless network of the guy in the next office, and was able to QVPN. So I know it is RRAS that is blocking it somehow.

    The other problem I had was once I was able to QVPN in, I could not access any of my computers on the other side of the WRV54G at home.

    What version of firmware is your WRV54G running?

    I tried it with the version currently available on Linksys.com, and I tried using the beta version.
