RV042 and Multiple IPs

    Hello. I have a couple of RV042 that I want to use to replace an aging router that breaks down too often, and I need a bit of help.

    My network setup has multiple incoming IP addresses and 3 subnets internally. I was able to successfully configure and test the subnets and communicate to all machine from within the network (inside to inside on different subnets) so I have no problem there. What I do have a problem with is IP forwarding.

    I configured the Access rules to forward ip:port requests from one IP to one internally (proper nat). It seems when connected, the only IP the router responds to is the WAN IP, and none of the other multitude of IPs that I own.

    Is there a way to make the RV042 respond to the IP range and forward the necessary packets to their destination?

    Example of problem: Assigned IPs, GW, Wan IP -nat-> set in Access rules. Router does not respond to Seen as dead IP to outside world.

    Is there no one else who has come up with such a problem or have any idea if the RV042 can support it?

    Are you talking about accessing internally or externally?

    I assumed the router can only hold two WAN address as it has only two WAN ports.

    Are you trying to pass the WAN ip's to an internal device?

    Yes. Although the router is programed with 1 IP in the WAN, I'd like it to respond to the other IPs that are directed to it. I figured setting up the firewall/nat to forward the other IPs to thier internal equivilents would make the router listen for those IPs as well.

    Is that possible, or am I trying to do the impossible with this type of router? (trying to save some cash instead of buying an expensive cisco router...)
