It sounds like you need to implement a group rule using 'add service service_name'.
ie.
service web1
ip address 192.168.1.1
port 80
active
service web2
ip address 192.168.1.2
port 80
active
owner vip
content web_servers
vip address 192.168.1.100
port 80
protocol tcp
add service web1
add service web2
active
group web_servers
vip address 192.168.1.100
add service web1
add service web2
active
What this should do is NAT any request *initiated* from web1 or web2 to the IP address specified in the group rule. In this case it is 192.168.1.100, the same as the content rule. This is fine, or you can use a different IP. I'm using RFC1918 addresses in this example, as 192.168.1.100 would be natted to some public IP on the firewall in front of the CSS.
If you wanted to do internal load balancing, or load balance to a service *NOT* within your environment (ie. 3rd party data center), you would simply change 'add service' to 'add destination service' in the group rule.
