How to route multiple IP addresses with IPTABLE command?

Hi,
We have a router and devices for testing. We route devices with below command

Code:
 
iptables -t nat -A PREROUTING -p tcp -d 0/0 --dport 80 -s 10.111.111.22 -j DNAT --to-destination 10.13.0.16:3128

where 10.111.111.22 is device IP. and 10.13.0.16 is our Linux box machine.
Likewise we are having 20 devices so 20 different IPs.

So, the issue is each time we need to copy paste above command with different device IP address.

My question is will someone please point me to command where I can have 5-6 device ip addresses together so, I can route 5-6 devices symultaniously?

I tried below but failed
Code:
iptables -t nat -A PREROUTING -p tcp -d 0/0 --dport 80 -s 10.111.111.22,10.111.111.23 -j DNAT --to-destination 10.13.0.16:3128
 
iptables -t nat -A PREROUTING -p tcp -d 0/0 --dport 80 -source 10.111.111.22,10.111.111.23 -j DNAT --to-destination 10.13.0.16:3128
 
iptables -t nat -A PREROUTING -p tcp -d 0/0 --dport 80 -source 10.111.111.22 10.111.111.23 -j DNAT --to-destination 10.13.0.16:3128

Please help me in this case.

NAME
bouncesaying - perhaps bounce each incoming message SYNOPSIS
in .qmail: |bouncesaying error [ program [ arg ... ] ] DESCRIPTION
bouncesaying feeds each new mail message to program with the given arguments. If program exits 0, bouncesaying prints error and bounces the message. If program exits 111, bouncesaying exits 111, so delivery will be retried later. If program exits anything else (or does not exist), bouncesaying exits 0, so the rest of .qmail will be processed as usual. Note that it is not safe for program to fork a child that reads the message in the background. If program is not supplied, bouncesaying always bounces the message: |bouncesaying 'This address no longer accepts mail.' WARNING: If you create a .qmail file to enable bouncesaying, make sure to also add a line specifying delivery to your normal mailbox. SEE ALSO
