NAT with RV042?

    Hello.

    I have a big problem with NAT on the RV042.

    At First my Network:

    (2x Internet connection) RV042 (10.1.0.1) >> (10.1.0.2) SuSE Linux 8.2 (10.2.0.1) >> (10.2.0.x) Internal Network.

    Now... If i config the RV042 in Gateway Workingmode (setup > Advanced Routing) and make an static route to my internal network (Destination IP: 10.2.0.0, Subnet Mask: 255.255.0.0, Default Gateway: 10.1.0.2) my internal Network does not connect to internet.
    If i config the SuSE Linux firewall to "forwarding" the connections with NAT my internal network connecting to the internet.
    There are many Problems with VPN connections from internal network over the internet, but this is an other story.
    The Problem is: If i make a VPN connection over Internet TO RV042 with the QuickVPN program i can't connect my internal network behind the SuSE Linux, because the inernal network is not in the same network as the RV042.

    I have an other Dual-WAN Router from Netgear (FVX538) and can connect to internet without any NAT configurations on the SuSE Linux, and if i make an VPN connection over internet TO FVX538 i can connect every Computer on my internal network.

    Is there any one idea, how to solve this NAT problem on my RV042?

    I hope my english is not so bat and you can understand me...

    Have you enabled RIP on the RV042 and Linux at all?

    I have exactly the same issue here... Anyone found a solution?

    My setup:

    Provider routeur (69.70.60.1) <--> (69.70.60.2) RV042 (192.168.1.1) <--> (192.168.1.2) Gentoo box (172.16.3.1) <--> Internal network (172.16.3.x)

    I use RIPv2 on both RV042 and Gentoo box. It work because RV042 show route to my internal network (172.16.3.x).

    I can ping from internal network (172.16.3.200) to 69.70.60.2
    I can't ping from internal network (172.16.3.200) to 69.70.60.1
    I can't ping from internal network (172.16.3.200) to internet
    I can ping from gentoo box (192.168.1.2) to internet
    I can ping from RV042 (192.168.1.1) to internal network (172.16.3.200)

    My guess is RV042 not use routing table with masquerading. Bug or bad conf?

    Hello,
    i already reported this issue long time ago. With the new beta it is working but not for all protocolls, for example ftp and cvs does not do the job. HTTP/SMTP works well.

    I currently have a WRT54G in front of the rv04 as gateway and everything works, but this configuration won't work with the new Beta relase :(

    Default gateway is NOT 10.1.0.2

    The "Gateway" is the router that is connected to the internet. So it should look like so:

    Destination IP: 10.2.0.0
    Subnet Mask: 255.255.0.0
    Default Gateway: 10.1.0.1

    when you put the netgear up what routing table does that use?
