What's a better objection is that this range is just not enough. This
local-port range small enough to be painful on too many systems.
On my system, 2.4.0-test1-ac22-classzone, the default seems to be:
: tazenda 1 ; cat /proc/sys/net/ipv4/ip_local_port_range
32768 61000
Perhaps that should be changed to 49152/61000, but let's not keep the
braindamage of only having some 4000 local ports.
