http connection hangs when connecting to forwarded IP

[gerardo arnaez <garnaez@gmail.com>]

Hello.
Im using iptables to forward an entire Ip address

the set is

DSL <--->(eth1) Server A (eth0[192.168.1.1])<-->SWITCH<-->
[192.168.1.2](eth0)ServerB

ServerA listens on multiplle IP addresses
I want Server A to forward a specific IP addres to Server B as
if ServerB were directly connected to the internet

servA listens on 69.30.71.117 (alias eth1:1) 
I want it to forward al requests on this IP to server B
Server B is 192.168.1.2

From reading and going on line
I have the follow iptables rules
but when I try to connect to 6930.71.117 via a port 80 from outside the system
It just hangs.
Not sure where the trouble lays,
any help appreciated
the follw are my rules set

---------------------------
iptables -F
iptables -t nat -F
iptables -t mangle -F #ignore if you get an error here
iptables -X #deletes every non-builtin chain in the table
echo "table cleanup complete"

iptables -t nat -A PREROUTING -d 69.30.71.117 -j DNAT --to 192.168.1.2
iptables -t nat -A POSTROUTING -s 192.168.1.2 -j SNAT --to 69.30.71.117
echo "forward 69.30.71.117 to 192.168.1.2"
