If our ISP allocates a block public IP addresses for us, then we may use the public IP address with IP Routed Subnet or Routing Usage LAN. This article describes how to use a public iP address with Routing Usage LAN.
Suppose ISP provides a public IP subnet 184.108.40.206/255.255.255.252 for us, and the gateway IP is 220.127.116.11. The public IP addresses we can use are between 18.104.22.168 to 22.214.171.124. The following shows how to set up a non-NAT subnet so that the server behind Vigor Router can use the public IP address 126.96.36.199.
Go to WAN >> Internet Access and configure the WAN connection according to what ISP provides. (Note: If it is necessary to specify an IP address manually, remember that subnet mask for WAN interface should be larger than that of LAN interface.)
1. Go to LAN >> VLAN,
2. Go to LAN >> General Setup, click on Details Page for LAN 2.
3. Set up TCP/IP details for LAN 2,
4. For DHCP Server Configuration, we may either:
After finishing the above configurations, PC or Server that connects to Port 5 or Port 6 with IP settings as IP 188.8.131.52/ mask 255.255.255.252/ Gateway IP 184.108.40.206 will be able to access Internet through Vigor Router.
