Hi everyone,
A customer approached us with a unique issue,
He wants to get NAT type A or B to have a better connection to Nintendo's online services for Smash Brothers Ultimate (for school esports)
Typically on a home router, you would simply go the NAT/Gaming section and add port ranges that you want to allow. However, this client using a Cisco firewall, managed through ASDM running ASA code version 9.14.
I think we need some type of static NAT rule, but I'm not sure if "port forwarding" is needed. If so, how would I even do that on Cisco's platform? When creating static NAT rules it doesn't let you put in a port range.
The ports I want to be open are UDP 1-65535, and TCP 6667, 12400, 28910, 29900, 29901, 29920
We want to limit the exposure to any type of security risk, so wondering if there is a way to get around opening that many ports up on the UDP side.
