In that scenario, 1,200 forwards would be possible. And no, port exaustion isn't a serious concern for us. The kernel-level max of 35,535 (65535 minus 30000) would be per external IP, and some of our servers have 100+ IPs. So on our server with the most IPs (114), in order to exaust every port forward a person would need 4,050,990 (35535*114) forwards, which would require ~3376 lifetime tokens.
