Hiya,
I posted this to -questions but didn't get any responses so I'm posting
it again here.
I'm having problems with NAT crashing my FreeBSD box. This never
happened in 6.x but in 7.x it's predictable for me. Any time I use
either of my two NICs for my internal net my FreeBSD box hangs and
requires power cycling to reboot.
My guess is that some option changed between 6.x and 7.x and I simply
missed it, or that I have something configured completely improperly,
but after hours of tinkering I've yet to fix the problem.
Initially I figured it might be NAT in PPP which was causing the
problem, so I backed it out and used NATD but the same thing happens to me.
uname info: 7.0-STABLE FreeBSD 7.0-STABLE #0: Sun Jun 15 21:35:13 PDT 2008
my ipfw rules:
00100 0 0 check-state
00200 1678471 126337051 skipto 3000 ip from any to 69.229.113.78 in
recv tun0
00210 0 0 deny log ip from any to any in recv vr0
03000 61 4548 divert 8668 ip from any to any via fxp0
03100 0 0 deny ip from 192.168.32.0/24 to any in recv vr0
*snip*
My FreeBSD box runs PPP on vr0 and my lan runs on fxp0. I've switched
them and the freeze-up continues. The host on my LAN is 192.168.32.10,
my internal interface is 192.168.32.1 and my external interface is
69.229.113.78.
my /usr/local/etc/natd.conf:
#unregistered_only
#log_ipfw_denied
redirect_address 192.168.32.10 69.229.113.74
#punch_fw 25:50
interface fxp0
I commented out a few lines to test it bare-bones. No luck.
I added these to my kernel config, which is otherwise a very standard
GENERIC kernel config:
options IPFIREWALL
options IPDIVERT
the related entries from /etc/rc.conf:
ppp_enable="YES"
ppp_mode="ddial"
ppp_nat="NO"
ppp_profile="sbc"
gateway_enable="YES"
my /etc/ppp/ppp.conf:
default:
set log Phase Chat LCP IPCP CCP tun command
set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 192.168.32.0/24
sbc:
set device PPPoE:vr0
set authname MYUSERNAME@sbcglobal.net
set authkey MYPASSWORD
set dial
set login
set mru 1492
set mtu 1492
accept lqr
set crtscts off
set speed sync
enable dns
add default HISADDR
set log Phase Chat LCP IPCP CCP tun command
set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 192.168.0.0/16
# NAT
# nat enable yes
nat log no
# nat same_ports yes
# nat unregistered_only yes
nat addr 192.168.32.10 69.229.113.73
Again, NAT is turned off in PPP at the moment and I'm using /sbin/natd
Machine connects to the net and works great until I try to use the LAN.
the LAN works for a few seconds, maybe serving up a web page or two and
then...freeze up. The box will keep running for days until I use the LAN
at which point it freezes solid.
I never saw the machine recover from this situation though there is a
crash dump in /var/crash from late last night after I wasn't paying
attention:
# ls -lart /var/crash

any help, hints, clues or just a simple "how could you be so dumb, the

Thanks for taking the time to read and consider this.
