Routing functions UTM

Hi,

I need some help over here. On one hand, I got my production network (192.168.100.0/24) on the other hand my former test network (192.168.1.0/24). I have on both sites an Sophos UTM virtual appliance.
Now to my question:
Is it possible that the UTM take over the function of a router? I need to get from my production network over to my former test network, without changing my host ip address.

Thanks,
lenny
