    Hi,
    I've looked around everywhere and I haven't found a solution to my problem. I have an E2500 with 1.28 Shibby Tomato installed on it. Here is my dilemma.

    I have a DSL connection with 5 dedicated IP's this is a slow but business grade connection. The WAN port is tied to this network. Internet->DSL Modem->68.17.X.X network->Tomato Wan (68.17.X.1)

    The internal LAN ports tie into the office lan, the DHCP, DNS, WINS, ETC. is all handled by a 2008 Server. This network has a fiber gateway. Internet->Fiber Modem->10.168.1.X->Tomato Lan (10.168.1.1). DHCP on the internal network points everyone to the fiber modem as the gateway (except the Tomato), with the Tomato available as a backup. The fiber modem registers DDNS and has a port forward rule for all 1194 traffic to go to 10.168.1.1.

    OpenVPN connections through the static IP associated with the DSL Modem works fine. The connection through the fiber does not. I can see the packet getting to the Tomato Lan, but there is no response.

    From Wireshark I can see that the source IP is the address of the client and the destination is the Tomato Lan. Is there a problem in that the Tomato is going to try and route out through the WAN port and that gateway, not back through the Fiber modem? or is it not accepting traffic on the LAN ports? Any suggestions would be helpful.

    Thanks,
    Jim
