I need advice/clarification on the proper way to set up two routers in a network with multiple public IP addresses, please.
My local network has 5 public IP addresses (18.104.22.168 - 22.214.171.124) and I want to run separate routers for the internal and external networks.
My thinking was this...
On my external 10/100 router, I assign the LAN address 192.168.100.1, and the WAN address 126.96.36.199, with the gateway pointing to the ISP modem. Then, I use one-to-one NAT for my public servers using 188.8.131.52 - 184.108.40.206. The public server NIC's would get an internal address in the 192.168.100.x subnet, with the gateway of 192.168.100.1
On my internal gigabit router, I assign the LAN address 192.168.1.1, and the WAN address 220.127.116.11, with the gateway pointing to the ISP modem. The private network NIC's would then get an internal address in the 192.168.1.x subnet, with the 192.168.1.1 gateway.
Will this work?
Can I use the same public (ISP modem) gateway for the two routers, and just assign each router one of the public IP addresses?
Do I need to configure something special on each router?
Your assistance is truly appreciated!
Thanks very much.
