I have the Mikrotik RB750 configured using PCC to share to wan connections to my LAN.
The LAN is broken up into smaller VLANS, 172.17.0.0/24 is my backbone, where the servers are located.
172.17.8.0/24 Vlan 1
172.17.6.0/27
172.17.6.32/27
172.17.6.64/27
172.17.16.0/24
172.17.24.0/24
The Mikrotik LAN ip is 172.17.0.8
I have a Windows 2003 server which gives out DHCP to each of the vlans by way of IP helper or relay. server ip 172.17.0.121
If I put the gateway of the Server as 0.8 clients stop getting dhcp addresses. I tried to setup DHCP relay on 0.8. it shows it is getting DHCP requests but does not reply. I am new to the Mikrotik routers so am a little lost and cannot understand why this does not work. If I put back the cisco unit it works fine.
