I have hardware connected to router with DHCP server. That router has MAC reservation to make sure hardware be assigned to specific IP. When this setup isolated everything is fine, but if I connect WAN port of router to local network, hardware gets dhcp of primary domain controller(which is somehow far from haardware! not first host on way like 1st router). Why dhcp packets bypass my router? Is it something standard? How to avoid? Thanks!
1. [HW]<->[Router1/DHCP1] - Isolated network. HW get correct IP from DHCP MAC reservation: 10.23.205.89 2. [HW]<->[Router1/DHCP1]<--->[LAN]<--->[PDC/DHCP2]<--->[GW]<-->[Internet] - DHCP request bypass Router1 and gets IP from PDC/DHCP2 126.96.36.199 f.e.
