Yes, basically using Computer A to be an IP-level proxy. Note that the
source 
address as seen by Computer B will always be that of Computer A. If this is 
not a problem, you can use:

$IPTABLES -t nat -A PREROUTING -p tcp --dport 80 -d xxx.xxx.xxx.xxx -j DNAT 
--to zzz.zzz.zzz.zzz
$IPTABLES -A FORWARD -p tcp --dport 80 -d xxx.xxx.xxx.xxx j ACCEPT
$IPTABLES -t nat -A POSTROUTING -p tcp --dport 80 -d zzz.zzz.zzz.zzz -j SNAT

--to xxx.xxx.xxx.xxx

Drop the '--dport 80' bits if you want all traffic, not just HTTP to be 
proxied.

Cheers,
Gavin.
