    I'm on my second Wrv54g. The problem im having is trying to route a second network out to the internet through the wrv54g. I acts like it isnt natting the second network.

    I currently have to networks 192.168.10.x that is the network of the wrv54g, and another network 192.168.100.x that is connected to a cisco 2900 switch and is being routed by a cisco 2500 router. When i connect the wrv54g I get an IP from my ISP through cable modem, and I can connect my laptop to the wrv54g router and get to the internet. When i connect say lan 2 to my switch where my 192.168.100.x network lives, and configure a static route to this network in the wrv54g I can ping the 192.168.100.x network from the wrv54g and my laptop connected to the wrv54g, and from the 192.168.100.x network i can ping the wrv45g router and my laptop. When I try to get to the internet say google.com, or this site it just dies.

    I have a DNS server on my network and it will not resolve to any external address's like google ect unless I add the LAN ip of the wrv54g router as a forwarder, then it resolves but the computers still cannot get to the internet.

    I setup a syslog server, and pointed the wrv54g to the syslog server, and when I try to get to google.com from the 192.168.100.x network I can see the router except the connection out, but I dont see anything back, and once in a while I'll actially see something try to cme back and the router denies it saying blocking-rule.

    Anyone else have any issues with routing another network through their wrv54g?

    Currently I have an Linksys BEFSR81 router in place and everything work perfactly. Once I replace the BEFSR81 with the WRV54G I no longer can get to the internet from my second network.

    I'm not using VPN at this time just tryig to get the basic function of the router to work for me.

    Sorry for the long winded post.
    Any help greatly appriciated.

    No one with any info?

    I called Linksys about this issue and they were useless, they told me to return the device and get another which is why i'm on my second Wrv54g router now. So far as I can tell from a lot of other posts this device is pretty much a pos lots of issues and not enough support from Linksys.

    Haven't tried setting one up that way, but if the config is the same as on the BEFSR81 and that works then it points to a firmware issue with the WRV54G. If your not on the latest firmware version then try that, if you are then I guess it's either wait until Linksys release a new one that works or use a different product :?

    Pardon me for asking guys, but I didn't see this question throughout any of your posts: are you using a straight thru cable from your WRV54g to your cisco 2500 or are you using crossover? I realize this is a 101 question I'm posing, but I just thought I'd mention it because sometimes we tend to forget that not all linksys products have builtin crossovers...

    Seeing as he can ping devices from both sides it suggests that it's not a cabling issue ;)

    It sounds to me like your Cisco device needs a default gateway address to tell it how to get to the internet. a route should be setup to tell the Cisco device that all traffic that it does not have a route for should be sent to your WRV54G. This is normally the address.

    Hopes this helps.

    It is a strait through cable to a cisco switch. As it was mentioned I can ping all devices on the lan from both networks.

    The Cisco router does have a default gateway 192.168.10.x (being the lan address of the WRV54G router).

    I have this same exact setup with my Linksys BESFR81 router and eveything works fine.

    I found a post on I believe Amazon on the reviews about the WRV54G router that stated he was having the same natting issue with his WRV54G. I'll tell you reading these posts about this device I have never seen so many negitive things said about any device, I know a lot of the issues are probably user error, but it still is amazing how many negitive posts there are.
