how to configure dns slave and dhcp
Posted on 2012-03-19
We are implementing MPLS VPN (hub and spoke) HUB has fortigate300 firewall and Router (fortigate300 same box works as router and firewall, DHCP is disabled for the reason ubuntu linux working as DDNS )
HUB network subnet is 192.168.1.0/24
Linux DDNS is configured behind the fortigate300, presently for servers and other workstations static IP's are assigned
DHCP is enabled for the mobile devices laptops everything is working fine.
Now that implementation is going on and for one spoke the installation got completed the spoke subnet is of 192.168.11.0/24, 192.168.1.11.1 is the router ip.
Router used at spoke are Router 861 and at HUB the MPLS router is Router 1905 from here the termination to the fortigate 300
requirement is all the spoke locations should be able to access the HUB hosted applications like http, ftp and data and also few users should get internet from the HUB location
My doubt is here at HUB central office the zone files and dhcp is configured for 192.168.1.0/24 series now all the spokes are with different network starting from 192.168.11.0 in this case how to configure the DNS salve for different network
Can anybody help me how to configure for the below:
1. Setup a slave DNS server at each spoke, along with a DHCP server for that subnet that dynamically updates the master DNS server
2. Can both DNS slave and DHCP Server be configured on Router 861 at spoke locations is possible will ask the ISP technical support to configure accordingly
3. if above 1 is possible then how to configure Ubuntu Linux DDNS as of now working for 192.168.1.0/24 to work for all spokes of different network starting from 192.168.11.0/24 ----28/24 which all the configuration files to be worked on.
Thanks in advance.
