    Hi,

    We are succesfully using 1 RV082 connected to 22 RV042 in our remote branches.

    We want to add a second RV082 so we can "load balance" or have a failover RV082. We thus need help in routing configuration. Here is the scoop.

    Local Subnet 10.10.10.x on RV082 (RV082 is 10.10.10.254 mask 255.255.255.0) with 22 tunnels with RV082 in subnets 10.10.11.x, 10.10.12.x, etc. It is setup as a GATEWAY and connects to the Internet with a public IP on WAN1. Our servers are in 10.10.10.x and the remote RV042 cant connect without any problems. Many yrears working great.

    We want to setup the 2nd RV082 on the same 10.10.10.x segment and we have set it up as a ROUTER (not a GATEWAY), gave it a static IP address of 10.10.10.95 connected in same LAN as 1st RV082. Problem is that when a new VPN Tunnel is setup (10.10.21.x)..the connection works, but packets from the remote RV042 can not route to our 10.10.10.x servers. We tried ading a static route of 10.10.10.0, 255.255.255.0 with gateway 10.10.10.254 (first RV082)..but cant seem to work.

    Any ideas? The main thing is to have multiple RV082 connected on same LAN (only one acting as a gateway, others as routers). Each RV082 has a different public IP address but share the same 10.10.10.x subnet on the LAN side to connect to servers.

    It must be a stupid config. Thanks for your help! Anyone?!?

    Hi...any ideas...? We need to grow our VPN tunnels and want to use RV082 for 30 tunnels each..all connected to one subnet that has our servers? ideas?

    Thanks!

    Your servers are probably routing back to the wrong network, you can confirm whats going on with a packet analyzer like WireShark or TCPDump. You probably want to add a static route to the remote secure group on router #2 to router #1 as router #1 will try to route those IPs out to the internet because it doesn't know what to do with them, and your servers will use router #1 as the default gateway.

    seem diificult
    when a VPN is mounted between RV082 and another network
    RV082 add a route via VPN IF

    eg : LAN RV082 network is 192.168.1.0 , LAN on other network is 10.10.10.0
    when VPN is mounted , if RV082 is your default router if you want to ping 10.10.10.0
    RV082 route your request via VPN interface ipsec0
    so Yo can have only One route for thsi network on your LAN
    and thsi kind of VPN force to have same route on teh other side to be sure the reply request come back in the same way ....
