But there is also a fundamental limit of 2^16 = 65536 concurrent connections, right?
- 2fastpost 5y agoYes, from one NAT IP using the same protocol to a single public IP using a particular port. Change any of those and you can do 2^16 concurrent connections more per change. In other words, NAT works on the five-tuple of: protocol, source IP, source port, destination IP and destination port.
