Are the clients set to get a dhcp address?
When you say outbound are you trying to assign ips to people on the internet?
what is the "client side"? Wan or Lan?
"I never understood why the world loves DHCP so much."
#1. it scales to large networks
#2 centralizes ip administration
#3 allows you to update/change the ip plan dynamically
#4 allows you to do static ip assignments with ip reservations
#5 dynamically updates MS DNS
Why workstation static ips don't scale.
#1 static ip assignments require you to document and update that document any time a change is made. Labor intensive.
#2 does not scale with larger amounts of workstations
#3 labor intensive to then change to dhcp
Hopefully this will help your understanding.
