NAT one network to another using iptables

Question

Trying to NAT ips in different network using iptables.

KVM host with ip 10.10.11.36 on bridge br0.

Two vms are running with ip 192.168.11.60 and 192.168.11.57 sharing bridge br0.

Want to NAT all request coming on 10.10.11.60 to 192.168.11.60.

How can this be done with out using SNAT.

tried this:

On host bridge br0 created an alias br0:0 with ip 192.168.11.36 and specified this in guest as gateway.

NAT rule.

DNAT       all  --  anywhere             10.10.11.60         to:192.168.11.60

ofcourse rule counter is not increasing,

How to make NAT work here?

You mean All requests coming on 10.10.11.36 to 192.168.11.60? Since you never mentioned 10.10.11.60 I assume you made a typo. — Valentin Bajrami, Jul 17 '13 at 14:41
You still have not asked a question! Hint: a question is an interrogative statement followed by an eroteme (?). — Robbie Mckennie, Jul 17 '13 at 16:43
`ofcourse rule counter is not increasing,` Show us all your rules. — fukawi2, Jul 18 '13 at 07:20
Well if that is the case and that counter isn't going up, there are no packets reaching the box destined for 10.10.11.60 so the rule isn't your problem. — fukawi2, Jul 18 '13 at 08:11
