Good day! I have a task in the organization of packet transmission via TCP / UDP protocols by port forwarding to specific local ip, which arrive at the external ip. I have on hand 2 TP-Link TL-R480 +. One router can forward up to 16 ports. I need more. So, it turns out that routers, when working simultaneously with a single external IP, are in conflict, of course. How, using these hardware, can I get 2 different Internal networks with one external IP, so that I can additionally forward ports on one or the other Internal Network?

On TP-Link TL-R480 + in the settings as a broadcast port, you can specify a continuous range of ports. See emulator , Transmission - NAT - Virtual Servers. Accordingly, if the range of forwarded ports has a fused block of 16 (or less) ports, you can forward it to the second router as the first router, and then distribute it to customers one by one. And the remaining 15 ports on the first router are also distributed to individual clients.
However, it should be understood that some of the network’s clients will be behind NAT, so clients behind the first router will not be able to access clients behind the second router.

- Thank you for your reply! Tell me how then to form a subnet? if the first router has its own IP 11.2.0.1, which IP should be assigned to the second router, and which internal IPs should static ports be used on the PC in the subnet from the second router? - Maxim
- In addition, the ports I need on the IP of the second router can be specified in the range, and one rule on the IP. But then another problem arises, there are ports that fall within the range of other routing rules ... - Maxim
- if the first router has its own IP 11.2.0.1, which IP should be assigned to the second router Gray. He's private. RFC1918 to help. which internal ip is the same. But do not cross over subnets. there are ports that fall within the range of other routing rules. Take care that there are no intersections. - Akina
