If you have several servers in the LAN side, and the ISP has assigned several Public IP addresses to your ADSL line for each server, you can consider the Multi-NAT function on TP-Link modems.

 
Here is an example you can refer to.
 
Needs:
5 Servers in the LAN side;
5 Public IP addresses are available for each server;
WAN connection type is Dynamic IP.
 
Configurations on TP-Link modems
 
Step1:
Open the web browser and type http://192.168.1.1 in the address bar and press the Enter button. The default username and password are both admin.
 
Step 2:
Manually configure Static IP address for you internal servers. Here in the example, we use 192.168.1.10-14.
 
Step 3:
On the top menu, please go to Advanced Setup ->NAT, select your current PVC. Select Multiple and click IP Address Mapping(for Multiple IP Service).
Notes: If the Virtual Circuit is incorrect, there will be no options. You can go to Status page to check which PVC you are using. Usually, there are IP parameters behind the correct PVC.
 
Step 4:
Add five rules like the picture below:
The first rule’s public start IP is 0.0.0.0, it is for modem’s WAN IP:88.34.223.22.
 
With such settings, when visit the Public IP, the connection will be forwarded to the internal matched server directly.
