Hello All

I have looking for any specific answer for one thing.

I have a virtualized Server with only one physical interface eth0 (WAN). To run OpenVPN i need to use DHCP server. And here is the question: is there a chance to run DHCP server on eth0:0 interface? Or it is impossible ?

Thanks in advance.

From the EL6 Deployemtn Guide: https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Linux/6/ht...

"If a system has three network interfaces cards -- eth0, eth1, and eth2 -- and it is only desired that the DHCP daemon listens on eth0, then only specify eth0 in /etc/sysconfig/dhcpd" DHCPDARGS="eth0"

So in your case, edit the file /etc/sysconfig/dhcpd and set:

DHCPDARGS="eth0:0";
