first off--that is an *_ANCIENT_* version of iptables...1.2.8/1.2.9 is
the oldest version i still see in use regularly, as SuSE and RH are
keeping them around...however--the current version is 1.2.11...

anyways--it sounds like you compiled a custom kernel w/o MASQUERADE
support.  does your kernel config have the following set:

  CONFIG_IP_NF_TARGET_MASQUERADE=m

the 'm' would be for a modular kernel, a non-modular kernel would have
it set to 'y'

if you do have that set in your kernel, and your kernel is modular,
check the output of:

  lsmod | grep ipt_MASQUERADE

and if you don't see any output, try loading it with:

  modprobe ipt_MASQUERADE

the module in question should be located at:

/lib/modules/`uname -r`/kernel/net/ipv4/netfilter/ipt_MASQUERADE.o

HTH...
