I am aware of setting IPTABLES I have done it on non xen machines.Some
one who have done it on a server that runs Xen please share some thing
as how should I go for it.
The Dom0 will be having a public IP and I want all the DomU traffic to
masquarade through it.
Some sample configurations may help.

Is your intention for those DomU's to be accessed from the outside or just that they can access the outside?
If it's the latter you can use the network-nat and vif-nat scripts included in Xen. If it's the former you need to have

all DomUs come up on the same bridge, then create a dummy0 interface and add it to that bridge and create 
firewall rules to direct traffic in and allow it back out.

Some people, when confronted with a problem, think "I know, I'll use Windows." 

Now they have two problems.
