WRV54g VPN Client setup. Confused

    I am trying to remotely configure a VPN for a client, and when I go to add a user using the VPN Client Setup interface in the new 2.38b firmware I get the following dialog:

    "In order to ensure proper functionailty, the router will need to change its IP address 10 10.x.x.1 to avoid conflicts with the remote network. You will need to reboot all pc's...."

    Huh? Why is this? I have many static ip's on this network all routed to 192,168.1.x and there is no real way I could redo the entire network topology easily nor remotely. Why is the router requesting it's IP range change? Is there a way I can get around this? Do I need to perform the VPN setup on site as opposed to Remote Access?

    Don't sweat the technique :)

    The router does this to ensure you don't run into the possibility of having the same 192.168.1.XXX as someone else because alot of people still don't change the default ip address.

    Having said that, all you need to do is change your ip addressing scheme for the wrv54g "AS SOON AS YOU PUT THE ROUTER ONLINE!" By doing this, you can change your router ip scheme again and it "WILL NOT" force you to change it when you add your first vpn client.

    Do the following:

    - Change your wrv54g router's ip address to (let's say....)
    - After you've done that, add your first vpn client and save changes
    -- Notice how the router does "NOT" force you to change the ip scheme
    - Once you've added your first vpn client, change the router's ip address to match the ip scheme that is already in place


    I'll check back later to see if you post as having problems...

    Well I have been having nothing but headaches with this router since it came out of the box...

    Installed router at client's site, was there for 4 hours doing work no problems. The client comes back to work in the morning, and only half of the PC's are getting online. Against my urgings to the contrary, they plugged in their old wired router, and all computers had 'net access again. Basically the router appears to have some severe problem every 18 hours. Am running the most recent (NON BETA) firmware...

    What I have done for now is connect the wrv54g router to their existing router and use the VPN passthrough on it, to establish the VPN with the wrv54g router. In doing this, I figured I would have to change the ip scheme, and used the "VPN Client Access" utility to add myself. Upon doing so, I got the same warning as I mentioned above-but I did indeed need to change my IP range and chose OK. However, I diod not notice it didn't give me a full ip address. I am now unable to get to the router, because I do not know it's address. When I chose yes, what is the default "10.x.x.1" scheme? I've tried - all nothing.

    Sorry for the long post, but this is one of the craziest installs i have been a part of The netgear routers I have used in the past for VPN setups are much more intuitive

    it ain't that bad. The WRV54G is a class act if you understand how to talk to it "nicely" :)

    The solution is to set any of the computers on the wrv54g's segment to "obtain ip address automatically." This will tell you the wrv54g's ip address if you have it set to dhcp. Worst case as you probably know is to reset it to factory default and try it again.



    Netgear?!?!?! Pffffft...

    Ok, this setup appears to be the only configuration that will work. Once again, the wrv54g took itself offline, and I have reverted back to the Wired Linksys router. On the "wired" router (I dont have the model name in front of me) I have enabled the VPN passthrough. I have the wrv54g as a client to the wired router with the ip of ''. I want the WRV54g to act as the VPN server, and the Wired Linksys to act as the passthrough. This way, I am not putting a problematic router (I seriouslly doubt its the router, it is something the users are doing but I cannot get them to help troubleshoot the issue) as their internet access.

    I am guessing I need to setup a port forward to the wrv54g from the default wired router ( Is this correct? If so which port does quickvpn use to establish the vpn connection?

    I would ideally like to use the wrv54g as the replacement router, but have been unable to determine why it "dies" after 18-24hrs.
