No, for *BSD sysctl -w kern.maxfiles=<maxnumbers> is enough.
But you have to reconfigure and rebuild squid after that since the maximum
number squid uses is hardcoded into the binary.

But since *BSD defaults are quite high (eg. >1700 for 32 users on NetBSD)
I think something is going really wild here:

IIRC a router made the redirection of port 80 to the squid.
But if squid fetches through the router there must be an exception of the
redirection rules for the squid box to prevent squid's fetches to "bounce"
back from the router.

I guess such a loop could result in a big filedescriptor-eating of squid.
