Maximum number of "tun" pseudo-devices

I'm running a busy FreeBSD-based that may handle large numbers of
simultaneous connections. I'm currently using software that creates
a "tun" device for each connection. However, after it hits tun127
(128 pseudo-devices), it doesn't seem to want to create any more.
What sets the limit on the number of "tun" devices that can exist
in the system, and how can the limit be adjusted? Is there a
similar limit on, say, "ng" devices?
