I thought I had a simple setup here, but for some reason my one-to-one nat stops working every few hours. If I reset the router, or even turn a firewall rule on/off that is enough to make it work again. By "not working" I mean I am no longer able to access the internal IP from outside our network using the public IP defined in the one-to-one NAT. The one-to-one NAT just redirects to a secondary web server. Here is my setup:
I have 2 public IP's as follows: IP 1: 184.XX.XX.166, Gateway: 184.XX.XX.165, Subnet: 255.255.255.252
IP 2: 96.XX.XX.190, Gateway: 96.XX.XX.189, Subnet: 255.255.255.252
184.XX.XX.166 is configured as the WAN1 static IP. The one-to-one NAT has 96.XX.XX.190 going to internal IP 192.168.1.106.
These are the only settings I have changed on the router, other than 3 port forwarding rules for the primary public IP to direct to another private IP.
I did find another post where someone mentioned having this same issue, but there were no replies as to why it would stop working every few hours.
I also understand that with this router the internal IP's need to be on the same subnet for one-to-one nat to work, and they are. The public IP's use different gateways though... could that be an issue? I called our ISP and they said the gateway should not be a problem, so now here I am.
It is the RV042 V03 with firmware version v4.2.2.08.
I have never seen this work properly when the WAN IPs had different gateways. The ISP should provide a block of IPs in the same subnet with the same gateway for this to work. Usually they provide consecutive IP addresses.
