Hello thanks for the response, The reason I want to have two different source IPS coming from seperate VLANS is because of the way our ISPS filtering works, they filter specific IP ranges that we assign students and guests, and they unfilter other ranges to give teachers access to services like youtube. So I would like the staff VLAN to NAT back to an address that our ISP doesnt filter and our student VLAN to NAT back to an address that they do filter. Thanks
