Hi,
I have tried to build ipfilter 4.1.6 as module and as part of kernel on FreeBSD 5.3 on amd64 but in both cases I have failed. When I use
option IPFILTER in kernel config this is what I get:

When I have tried to build ipf.ko this is what I get:
ld -warn-common -r -d -o ipf.kld.5 ip_fil.o fil.o ml_ipl.o ip_nat.o ip_frag.o ip_state.o ip_proxy.o ip_auth.o ip_log.o ip_pool.o ip_htable.o ip_lookup.o ip_rules.o ip_scan.o ip_sync.o

*** Error code 1
Stop in /root/ip_fil4.1.6/BSD/FreeBSD-5.3-RELEASE-amd64. *** Error code 1

I have tried recompling with -fPIC but when I do kld_load ipf.ko this is what I get:
sen# kldload /boot/kernel/ipf.ko
dmesg output:
kldload: can't load /boot/kernel/ipf.ko: Exec format error
kldload: Unsupported file type
kldload: unexpected relocation type 7
link_elf: symbol appr_check undefined
So, my question is: can ipfilter be used to NAT something like 7000 hosts on FreeBSD? Currently I have cisco 7206 that is running IOS 12.3(4r)T1 only IOS that has NAT inside CEF (otherwise CPU load is something like 80% with this IOS it is something like 20% for 7000 hosts). I want my amd64 only to NAT inside network (10.1.0.0/16) but when I have tried ipfilter
v3.4.35 that comes with freebsd5.3 (compiled with LARGE_NAT) it had poor
performance. (it could handle something like 120000 connections although vaules in ip_nat.h were much greater, maybe I have missed some other parameters?). Machine has two broadcom NICs so I don't think that is problem, can someone advise what to do to?

Are those CFLAGS=-O2, a standard compilation or is that something you added to the make.conf ?. Ive tried some optimizations myself well building the kernel and its modules and got a very sparse build of things they dont seem to build to well when being built with -O2 opts.
Good luck and best regards, check your /etc/make.conf -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (FreeBSD) Comment: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0xF7DF979F
