Hi

I have a problem connecting DHCP in Virtual Box.
I have configured the Router for DHCP but when i configure the Virtual Box Client WinxP & Tiny Core it giving different IP Address.
Here my configuration with the Router
fa0/0 ip add 10.0.0.1
R1(config)#ip dhcp pool ourpool
R1(dhcp-config)#network 10.0.0.0 /24
R1(dhcp-config)#de
R1(dhcp-config)#default-router 10.0.0.1
R1(dhcp-config)#dn
R1(dhcp-config)#dns-server 8.8.8.8

Virtual Box client
Winxp - DHCP but the ip address 192.168.55.103
Tiny Core - DHCP but the ip address 192.168.55.104

Instead of taking the DHCP in the GNS3 router 10.0.0.0 network it giving its own ip address. In static Ip address it's working and in VPCS DHCP it working also, only in virtual box i have the problem.

Anybody who know how to fix this problem. Any suggestion and advice are appreciated

Thanks

I started having the same problem. It was working fine. I came on here and on Oracle's support pages and after reading and trying I dont know how many different things, I just gave up. Then I noticed one day that if you setup a VirtualBox Guest and launch the OS straight from there, without running Virtual Box Manager...it then works. How or why?? I dont know, but it does that way.

Hope this helps ya a little at least.

O.

I think you have running dhcp-service in your OS. Your VMs taking dhcp offer from that service. For example I had that issue after VmWare player installation
