If one of your public IP address will be used for only one device in the LAN, and another public IP adderss will be used for all devices in the LAN, then you can choose the router that support one-to-one NAT. As I knew, TP-Link router supports this function.

Dear Andone. 

 

Thank you very much for your reply. 

 

If I udersntand you correctly, you mean that ALL tp-link routers have this feature. 

Well, my current TL-R600VPN  does not. This router does not allow to specify second public IP alias. 

 

I need gigabit speed. 

 

I need to send all traffic (80 and 443 to be more precise ) from one public ip to one server on lan and all traffic from the other public IP to the second server in lan. 

 

I really dont know which router can do that. This feature should be names multi-nat but i cannot find such. 

 

:-(

 

Thank you very much.

If you are using R600VPN V4, then you can refer to the following picture to find the function. If you are using other version, I think they don't support this function and maybe cannot achieve your demand.
