Hi Swamy, Thanks. I checked the below configuration on router VM. 1. The VM's MAC and IP indeed being recorded in /etc/dhcphosts.txt file correctly; 2. The DHCP range configuration in /etc/dnsmasq.conf is below (seems to me it is not correctly configured): Dhcp-range=10.60.176.1, static
In my case, "10.60.176.1" is my default gateway IP, and my router VM IP address is "10.60.176.103". I am confused. Should it be "dhcp-range-10.60.176.103, static" ? Or, CS has the dhcp range for default network as "10.60.176.100 - 150" for example, my logic would be that, CS pass these information to router VM, correct? So would this dnsmasq.conf file be something like below ? : Dhcp-range=10.60.176.100,10.60.176.150,24h On my guest VM, if I do "dhclient eth0", it gets the new IP address from my external DHCP server, but not the one assigned by CS.
