Multiple WAN IPs to different ports/zones

Question

I am fairly new with using a Sophos UTM. I have a /29 block of public IPs with the first IP in my WAN configuration and the other 4 IPs in the additional interfaces under it. I have internet working fine on Port 1 using the first public IP in the block of x.250 with an internal of 192.168.10.1. What I am trying to figure out is setting it so Port 8 will use the next public IP of x.251 and an internal of 192.168.20.1. How do I go about configuring it so that the zone associated to port 8 will use the x.251 for the WAN traffic?

Hi William, 
 insert the additional WAN-IPs under Interfaces and Routing ->Interfaces -> Additional Addresses , then define different masquerading rules under Network protection -> NAT -> Masquerading for your different internal networks. 
 (my UTM "speaks" german, so perhaps the definitions above are a little bit different ;-) )
