Let me thank you folks in advance for helping me out.
I've just upgraded the OS and just installed another ethernet card and
turned on natd, almost exactly as the instructions say.
Now I get an unusual occurence. Everything associated with email very
slow. Sending email is slow, even mailq is slow:
$ time mailq
/var/spool/mqueue is empty
real 1m20.417s
user 0m0.059s
sys 0m0.012s
Specifics:
$ uname -a
FreeBSD dsl-146-127.resnet.purdue.edu 4.5-RC FreeBSD 4.5-RC #0: Thu Jan 17 06:38:45 EST 2002 dedrick@dsl-146-127.resnet.purdue.edu:/usr/obj/usr/src/sys/DSL-146-127-2 i386
/etc/rc.local:
/usr/sbin/sshd
/usr/sbin/lpd
/usr/sbin/lptcontrol -p
/usr/sbin/rndcontrol -q -s 2 -s 3 -s 1
/sbin/ifconfig dc0 192.168.0.1 media 100baseTX
/sbin/ipfw -f flush
/sbin/ipfw add divert natd all from any to any via ep0
/sbin/ipfw add pass all from any to any
/sbin/natd -interface ep0
/usr/local/apache/bin/httpsdctl start
Unfortunately the card dc0 has some sort of autosensor that switches
between different media. I can't get it to work unless I manually
tell it which media to use, hence dc0, the firewall and natd are all
configured as lines in /etc/rc.local.
$ ifconfig
dc0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500

faith0: flags=8002<BROADCAST,MULTICAST> mtu 1500
As I said before, most everything seems to be working fine, 'cept for
really slow mail related processes.
Also, on a probably unrelated note, when I plug dc0 into a switch, the
hub says that dc0 is transmitting like mad, which seems odd,
expecially when there are no other devices on its subnet with which it
should be communicating (all of my other devices just say "link"). Is
this normal behaviour?
Thanks again for your help.
