I got asked by a customer about handing out random UDP ports through a Cisco 831 router running DHCP and NAT. Apparently this is common in the gaming world. It is not something I have seen before. Can the customer do this with an 831? Apparently, it also works on the 67X series of DSL routers.
If you are referring to the router translating the users to a designated address on a random port, then this is accomplished by PAT (port address translation).
Is he providing a gaming server, or he want to allow game traffic in/out of his network ??
You can use NAT or PAT to achieve a translation to a public address.
Game traffic in and out of his network. I hadn't thought about PAT. That is probably the answer.
Thanks!
