Listen on Multiple IP's in HAProxy?

I have 3 IP's pointing at my load balancer. I currently have it setup to listen for one IP 10.0.0.10. How would I setup it up to listen on all 3? Do I just need to define another webfarm? I have included my haproxy.cfg

Code:

 
   
global

       uid 99
       gid 99


       daemon
   defaults


       mode http

       retries 3


       option redispatch
       maxconn 10000
       contimeout 10000
       clitimeout 50000
       srvtimeout 50000

   listen webfarm 10.0.0.10:80

       mode http
       stats uri /haproxy
       balance roundrobin
       cookie webpool insert
       option  httpclose
       option forwardfor
       server WWW1 10.0.0.20:80 cookie webpool_WWW1 check port 81 
       server WWW2 10.0.0.30:80 cookie webpool_WWW2 check port 81 
       server WWW3 10.0.0.40:80 cookie webpool_WWW3 check port 81 

   listen https 10.0.0.10:443     
       balance source
       mode tcp
       server WWW1 10.0.0.20:443 check
       server WWW2 10.0.0.30:443 check
       server WWW3 10.0.0.40:443 check

Thanks in advance for your help
