Netscaler Knowledgebase

I currently have a nestscaler setup that has one outside network and two inside networks.  So something like this:
outside: 66.1.1.1/27
inside1: 192.168.1.0/24
inside2: 192.168.2.0/24

I currently have this line in my config:
set rnat 192.168.1.0 255.255.255.0 -natIP 66.1.1.3

This works great for hosts on the inside1 network trying to reach the internet (mostly http api calls to third party sites) but it causes anything travelling from inside1 to inside2 to also get nat'd. 

Is there any way to have the NAT only take affect for traffic from inside1 -> outside, and not affect inside1->inside2?
