Can someone tell me which transport protocols and ports this uses or can be configured to use? Moreover, do clients have NAT traversal capabilities (no pun intended)?

This is always so hard to figure out for B2B libraries.

It supports clients connecting over TCP (which can be encrypted) and Websockets (can also be encrypted), you can configure it to pick on any port you want and it works through Network Address Translation (see https://docs.nats.io/running-a-nats-service/configuration#co...). Even supports MQTT clients directly (https://docs.nats.io/running-a-nats-service/configuration/mq...)
