No, ethernet switch works at lower / physical / MAC layer, NAT is 'above' that;
so as long as everything is OK with your TCP/IP settings everywhere,
a switch is entirely transparent to TCP/IP (or generally, when it's encapsulated
into MAC traffic).
All that happens at a level totally transparent to the TCP/IP stack
In a way, an Ethernet Switch is /the/ network near you, your cables are 'just' interconnects.
