Hi Lubor Kacian , 
 ether you bridge your WAN interface with another port on your Sophos or you put a simple switch between your ISP modem and Sophos, where you connect your Sophos (WAN port) and the Cisco (WAN port) to it.

You just have to add the desired IP as fixed on your Cisco device and thats all (with your /28 subnet mask)
