Clients shouldn't have too much trouble with NAT anymore, but there
might still be corner cases. The main firewall issue is that we use UDP,
which cannot reliably be tracked, so our defaults are set low enough to
reprobe all servers within 3 minutes which is about the time that a
Linux netfilter/iptables based firewall remembers the redirection.

If the firewall does not keep the redirection around, it is possible to
use a fixed port on the client side and configure the firewall with a
static NAT redirection which maps a fixed port on the firewall to the
specific local IP adddress/port of the Coda client.
