Having troubles with the network setup

Post by reggler »

Hi,

I want to allow my virtual machine to vpn into my company's network and since the vpn is PPTP i can't use NAT.
This is what I've tried:

I made a static bridge vbox0 and tried "Internal Network" this way. My ifconfig looks like:

Code: Select all

br0       Link encap:Ethernet  HWaddr 00:1C:25:03:B0:F3  
          inet addr:192.168.0.234  Bcast:192.168.0.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1              
          RX packets:39235126 errors:0 dropped:0 overruns:0 frame:0       
          TX packets:24210380 errors:0 dropped:0 overruns:0 carrier:0     
          collisions:0 txqueuelen:0                                       
          RX bytes:4260665981 (4063.2 Mb)  TX bytes:2080207323 (1983.8 Mb)

eth0      Link encap:Ethernet  HWaddr 00:1C:25:03:B0:F3  
          inet6 addr: fe80::21c:25ff:fe03:b0f3/64 Scope:Link
          UP BROADCAST RUNNING PROMISC MULTICAST  MTU:1500  Metric:1
          RX packets:100090730 errors:0 dropped:0 overruns:0 frame:0
          TX packets:61604594 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100
          RX bytes:3474922911 (3313.9 Mb)  TX bytes:38143047 (36.3 Mb)
          Memory:effc0000-effe0000

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:698762 errors:0 dropped:0 overruns:0 frame:0
          TX packets:698762 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:2651612598 (2528.7 Mb)  TX bytes:2651612598 (2528.7 Mb)

vbox0     Link encap:Ethernet  HWaddr 00:FF:35:00:A0:F1
          inet6 addr: fe80::2ff:35ff:fe00:a0f1/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:5969 overruns:0 carrier:0
          collisions:0 txqueuelen:500
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
The problem is, when i put vbox0 as network name, the guest is not able to acquire an IP from the DHCP server(external router).
Okay I said, let's try the "Host Interface" version then:
I tried to assign the tap to my user with:

Code: Select all

linux-c73s:/home/reg # sudo tunctl -t tap0 -u reg
Set 'tap0' persistent and owned by uid 1000
linux-c73s:/home/reg # sudo tunctl -t tap1 -u reg
Set 'tap1' persistent and owned by uid 1000
because I get the error "VERR_HOSTIF_INIT_FAILED" when i try to start my virtual machine with "host interface" networking.
What am I doing wrong? I went thru the documentation a couple times but i didn't see what I'm missing.
Help would be appreciated!
I'm btw working on an opensuse 11 system - not sure if this matters...
Thanks!

As this is more about Linux, I'm moving it to Linux Hosts.

Other points. Internal Networking, did you really read the manual? It clearly says that that option is used for communication between virtual machines, the Host is not aware of that network so it's obvious you won't get a DHCP reply from a router that is not part of the network.

Host Interface, you already have a host interface, namely vbox0 as shown in your ifconfig output. Just enter that name in the interface name box. Now start the VM and see if it boots normally. Then check if you actually have an IP address. It should get one.
Read the Forum Posting Guide before opening a topic.
VirtualBox FAQ: Check this before asking questions.
Online User Manual: A must read if you want to know what we're talking about.

See the Tutorials and FAQ section at the top of the Forum for more guides.
Try searching the forums first with Google and add the site filter for this forum.
