Facing issue with Fedora guest on windows 7 host

[Ashish Kumar]

We are using Windows 7 x64 as host and Fedora 23 as guest where we are using a VPN connection to connect with remote sites. We are facing some issue in that and below are scenarios which are working for us and which are not working

We are using "bridged" network for LAN and "Host only network" for data card.

1.) We are able to access all the sites on guest after connecting to VPN while we are using Local network on host.
2.) We are able to access all the sites on guest after connecting to VPN while we are using wireless network on host.

Issue :-

While we are using data card on host with sharing the connection, We are able to access the internet and able to connect with VPN as well. 1 link is accessible but 2 links are not working. We tried this on another system with same configuration and settings and able to access the links on guest without any issue.

Oracle vbox version 5.0.22 r108108 same on both the machines

Once more thing that It's working on few laptops like we verified it on 3 and from them it is working fine on 1 but not on other 2.
