hi all

Im afraid i am again with a very simple/stupid question :), even
though things not clear to me yet.

im droping/blocking certain sites mainly gator sites on my
router/firewall to LAN users, using slackware kernel 2.4.26.

im doing this with the below rule
$iptables -t nat -A POSTROUTING -s 0/0 -d  212.4.208.105 -j DROP
   This is working fine, however im kinda confuse whether this is the
proper table/chain for accomplished this or may I do it with FORWARD
chain like ...

  $iptables -A FORWARD -s 0/0 -d 212.4.208.105 -p tcp -j DROP

which approach is recommended ?
1)nat/POSTROUTING 
OR
2) FORWARD

thanks in advance

regards
Askar
