RV042G one-to-one NAT problem

Dear All

I purchased RV042G and setup one-to-one NAT problem to several servers. Sometimes the NAT servers lost the internet connection. My case as below

ISP provide two set Public IP Address , one modem

e.g.

set one) 100.100.1.2-6, gateway 100.100.1.1

set two) 200.200.2.2-6, gateway 200.200.2.1

I set my WAN 1 as below

IP: 200.200.2.2

Gateway: 200.200.2.1

One-to-One NAT as below

Public: 100.100.1.2 > Private: 192.168.1.2

Public: 100.100.1.3 > Private: 192.168.1.3

All computers and servers (one-to-one NAT) outbound and inbound all work fine. After several hours, only the servers (one-to-one NAT) alert internet connection broken, but the computers (non NAT) still have internet connection.

What's the problem occurs? Why only one-to-one NAT servers lost the connection? and Why only serveral hours later, the server lost the internet connection.

If I changed the WAN setting to same as subnet of the one-to-one NAT, it doesn't occur any problem.

Thanks

Noel

You might want to check with your ISP to see if the configuration you want to achieve is supported.

It would appear that the IP addresses provided by your ISP are meant for two WAN connections.

WAN 1 IP: 100.100.1.2

Gateway: 100.100.1.1

One-to-One NAT as below

Public: 100.100.1.3 > Private: 192.168.1.2

Public: 100.100.1.4 > Private: 192.168.1.3

WAN 2 IP: 200.200.2.2

Gateway: 200.200.2.1

One-to-One NAT as below

Public: 200.200.2.3 > Private: 192.168.1.x

Public: 200.200.2.4 > Private: 192.168.1.y
