iptables & masquerading...

[Greg Sanders]

I just upgraded from a pre 8 beta to the current beta and it looks like
masquerading is borked...

[root at lanfest1 root]# iptables -t nat -A POSTROUTING -s 192.168.0.0/16 -o
ppp0 -j MASQUERADE
iptables: No chain/target/match by that name

[root at lanfest1 root]# lsmod | grep ip
ipt_REJECT              4024   0  (autoclean)
ipt_state               1080   0  (autoclean)
iptable_filter          2444   0  (autoclean)
iptable_nat            21816   0  (autoclean) (unused)
ip_conntrack           27208   2  (autoclean) [ipt_state iptable_nat]
ip_tables              15776   6  [ipt_REJECT ipt_state iptable_filter
iptable_nat]

[root at lanfest1 root]# modprobe ipt_MASQUERADE
/lib/modules/2.4.21-20.1.2024.2.1.nptl/kernel/net/ipv4/netfilter/ipchains.o:
init_module: Device or resource busy
Hint: insmod errors can be caused by incorrect module parameters,
including invalid IO or IRQ parameters.
      You may find more information in syslog or the output from dmesg
/lib/modules/2.4.21-20.1.2024.2.1.nptl/kernel/net/ipv4/netfilter/ipchains.o:
insmod
/lib/modules/2.4.21-20.1.2024.2.1.nptl/kernel/net/ipv4/netfilter/ipchains.o
failed
/lib/modules/2.4.21-20.1.2024.2.1.nptl/kernel/net/ipv4/netfilter/ipchains.o:
insmod ipt_MASQUERADE failed

Is this a known issue with the stock kernel, am I doing something wrong or
what?
