NAT network loses connectivity after using p2p like program
|Reported by:||kidault||Owned by:|
Host: win7pro, guest: winXP home
Yesterday, I made a snapshot and installed Xunlei(an download accelerator with p2p function, popular in China). After starting the program for 2 or 3 hours, the guest OS lost the NAT connectivity, while the host-only network was still working fine. The traffic mainly passed through the NAT adapter.
Ping to the NAT gateway(10.0.2.2) received no response. After I released the network address and renewed it, I got the "An error occurred while renewing interface LC : unable to contact your DHCP server. Request has timed out." message.
The problem has happened twice, in exactly the same routine.
I have setup a socks proxy on the host and run the Xunlei for about 10 hours. There is no problem with host-only adapter.
The problem seems to happen around 02:13:52.669 in the log. I remember that when I noticed the loss of network connectivity, I release and renew the NAT adapter, get some information in chinese, like "the adapter has gotten an address the same as another adapter on the network, this adapter will be disabled"(translate from Chinese to English, not very exact). Several minutes late, when I tried the release and renew of NAT adapter process again, I got the "An error occurred while renewing interface LC : unable to contact your DHCP server. Request has timed out." message.
