Network Delay with NAT network

Reported by: Thomas Williams Owned by:
Component: network/NAT Version: VirtualBox 3.1.2
Keywords: Cc:
Guest type: other Host type: other

Description (last modified by Frank Mehnert)

I'm getting a slow network on certain occasions when using NAT.

For example, if we ping a server which we usually get 20-30ms on from any other machine, the VirtualBox will get 20-30ms responses for the first three pings, then 500ms+ for the next 3, and then back to 20-30ms.

I've tried changing the device manufacturer but it didn't seem to work.

Changing it to a bridged network worked, however, we then experienced problems with our network outside of the VirtualBox.

I'm running OS X Snow Leopard (Latest) with Viscosity OpenVPN. The VPN has Windows XP 32Bit installed on it.

Actually, with either mode we experience network problems on the Host OS. Our traffic to our mail servers is routed over a VPN, yet when we boot the VirtualBox, some of our email boxes time out, whilst others still work. It's very intermittent, as soon as the VirtualMachine is shut down, it works fine.

Regarding your problem: Ping is not a valid test as ICMP is implemented but may have some issues. Do you experience such delay with regular traffic (ARP, TCP) as well?

Actually the ping issue was resolved in VBox 3.1.8.
