can't reach one of two gateways behind RV042 anymore

    can't reach one of two gateways behind RV042 from LAN anymore

    My setup:
    Internet <-> WAG300N (192.168.1.1) <-> (192.168.1.2) RV042 (192.168.2.2) <-> WRT54G3G (192.168.2.1) <-> Internet
    LAN is 192.168.0.x/24 and is connected to RV042 which LAN IP is 192.168.0.1
    [See the attached drawing]


    My problem:
    I've always been able to reach both WAG300N and WRT54G3G through RV042 from my LAN. Now I can reach only WRT54G3G and I can't reach WAG300N from my LAN anymore. I can still reach WAG300N from the Internet. What's the most interesting is that by typing WAG300N IP address (192.168.1.1) on the LAN I get instead web interface of RV042...
    Any ideas what the problem is?

    Do you have a management port number set for your RV042?

    Yes. It's set to 80. Why do you ask?

    Sorry,

    been certification testing. Now, where were we....

    What is the basis of your configuration, meaning, what exactly are you trying to do?

    I see you've got "routers behind routers;" what's your end goal? :)

    What's my goal? As always - a working network :) I have two gateways (WAG300N for DSL and WRT54G3G for UMTS) connected to RV042. I've always been able to log in to both gateways from my LAN. One day something happend and now I can only log in to WRT54G3G and not to WAG300N anymore. When I put WAG's local ip address in my browser (192.168.1.1) I get somehow redirected to RV042 instead (which has three ip numbers; 192.168.0.1 from LAN side, 192.168.1.2 from WAG side and 192.168.2.2 from WAG54G3G side). In the same time I can log in to WAG from the same computer but using it's public ip address not a local one.

    Okay,

    the drawing of your LAN is confusing me. Here's how I would illustrate my LAN configuration:

    Cisco 871W---modem---->INTERNET<---modem----linksys wrvs4400n


    If I were running a border router and an interior router, I'd describe it as so:

    Cisco 871W---modem--->INTERNET<---modem---wrvs4400n---wrv200

    Could you re-illustrate your network on more time in the following format?

    From what I could tell this is what his network looks like:
    [​IMG]

    What is the IP address of one of the computers on the LAN, I have a huntch that your RV042 reverted back to 192.168.1.1. You may also want to try to set the management port to 8080 instead and see if 192.168.1.1 brings up the WAG300N.

    Take a look at cfinic's drawing. That's how it looks like. However there should be 3 ip addresses near RV042 - 192.168.0.1 is from LAN side, 192.168.1.2 is from WAG300N side and 192.168.2.2 is from WRT54G3G side.

    Thanks to all trying to help me with this problem.

    Lately I had a new very serious problem with my RV042 - it stopped getting DNS entries from both gateways (WAG300N, WRT54G3G) connected to it. I tried and restored RV042 to Factory Default and then re entered all settings back. Guess what - by doing this both problems were solved.

    That's really pitty Linksys can't get any of its devices working stable. That is a shame taking into consideration these boxes are just crippled Linux systems. That's unbelievable how any company in the world can prosper making such low quality products.

    My idea: Make the CEO of Linksys read this site for just one priceless working day and let's see what happens next... :biggrin:

    After a few days the problem came out again... It's driving me crazy. Any thoughts?

    I take it the RV042 is loosing DHCP from the two routers? or do you have static IPs on the RV042 WAN ports?

    tbh I would use the 192.168.1.1 ip address for the RV042 LAN since this is a default and permanent setting for the RV042 QVPN settings from being told this some time ago if my memory servers me correctly.

    Set the two WAN IPs on the RV042 to Static ones with the relevant DNS entries as well. this should help.

    I have DHCP on both wan ports. It's not loosing ips but simple don't get them (don't accept would be maybe a better word)

    Permanent setting? I don't get it. Could you elaborate a little more, please?

    But DHCP is supposed to work in RV042 :) It's one of options in the user interface. I can send you a screenshot if you don't believe me. Just kidding.

    The problem now is not about not getting settings from DHCP. After reseting to the factory default it's working again. The problem is about not beeing able to reach one of two gateways behind RV042 any more. And what's strange I can ping this invisible gateway from LAN, traffic goes through it and what's the most strange I get RV042's home page when I put gateway's ip in my web browser...
