routing between public IP's using iptables

hello list,

i have got a linux machine configured as a router/gateway for my
internal network working abs. fine. i wanted to know is it possible to
route all the traffic coming from source (61.x.x.x) to the external
network of the gateway (132.100.200.128) to 210.204.124.138 (some
destination on Internet)

Who gave you permission to use those particular IP addresses? Or did you
just decide to use them on your own? That is "illegal"-- someone already
owns them and any traffic to those addresses will get routed to whoever
owns them, not to you. Use either 10.x.x.x or 192.168.x.x as your internal
addresses.

When you have done that, look at IP Masquarading In this the internal
machine addresses are translated to a range of port numbers of the one
gateway machine, and it acts as the traffic cop redirecting the packets.

well these public IP's are just choosen at random, to explain the
problem, the 2 IP's that i own are different. Let us assume that are
x.x.x.x and y.y.y.y and i want to forward any traffic comming from IP,
say (a.a.a.a) to x.x.x.x to be forwarded to y.y.y.y

Network address translation (NAT) is a technique of transparently
mapping an IP address or range to another IP address or range. Any
routing device situated between two endpoints can perform this
transformation of the packet.

my question is it possible to do that on the destination ?
