We were using a cisco with 1 IP address. We are now going to use a zyxel and a watchguard.
We have asked the ISP for a range of public IP's to use. 1 ip for wan of router 1 ip for lan of router and 1 ip for wan of firewall.
Now they have provided our internet address which they say to put on the wan interface of the router example
Now they have provided a completely different IP range 1 to go on lan of the router example
184.108.40.206 and one for wan of firewall 220.127.116.11. I have said to them i do not want to use nat on the router only NAT on the firewall and they have said I do not need NAT on the router, i do not see how traffic from the internet will route into my network without nat on the router or the router set in bridge mode or in the same address range as lan of router and wan of firewall. All our A records point at the IP on the wan interface of the router.
Am i missing something? will what the ISP say work and if so how will the router know to pass the traffic.
