hello all i come to you all with another question

i have 2 ip i need help with on my monowall

i have xxx.xxx.xxx.228
         xxx.xxx.xxx.118

now i have servers and stuff i want to use on ip 228

i want all the workstations to use the 118 ip, 

My ip's are static so in my wan connection i have the xxx.xxx.xxx.228 used in the ip address section
to make the connection in the static configurationportaion, follow me

so how would i make all my work stations use the 118 ip address and keep the 228 ip address for my
servers,
