How to forward more than 100 ports?

Question

System administration

The essence of the issue is in the topic)
Actually, it became interesting how to do this better, because in routers I noticed there are restrictions in the amount of up to 30, for example.
Standard connection thing:
White static ip 123.43.23.2:7777
Next, the router forwards the port to the gray ip
192.168.0.100:7777
But I need a lot of such connections
Maybe there is a solution in the form:
Connect to a certain PC from the Internet, and it in turn redirects connections for an unlimited number? Some kind of proxy...

Answer 1

You can forward ranges of ports or the entire ip, just use normal routers. Homemade, of course, are not designed for such perversions.
And don't forget the 65535 port limit. Need more - buy more ip addresses. Or even go to ipv6

Answer 2

If the router has such a limitation, it is rather a problem of the wretchedness of the interface of a particular router. It is technically possible to forward 65536, well, a little less ports. =)
In some routers, you can forward not by one port, but by ranges, perhaps in your case this will solve the problem.
Also in some routers you can configure DMZ, and perhaps this will solve your problem.

How to forward more than 100 ports?

As well as one - just specify the port, or the range of ports that you are forwarding. You can forward all ports with one rule.

Maybe there is a solution in the form:
You connect to a certain PC from the Internet, and it, in turn, redirects connections to an unlimited number?

Of course have.
This PC is called a router.
Therefore, find a router with a white address on the Internet, set up a VPN so that it is on the same network with you, and forward any ports you like.

Answer 4

describe your task - the chances of getting the right answer will increase tremendously. so far, judging by the question, the solution has nothing to do with forwarding at all, connect using VPN.
