I've never used Parallels, so here is only a very high level description how you could do it, in case the bridge doesn't work:
- Make sure the Windows system can reach the VPN portal (in your case this probably means: Windows has Internet access)
- Make sure the Windows system has a private IP address on a virtual network adapter, e.g.
192.168.12.34
on vmnet0
that you can ping
from OS X. It's okay if it's the same virtual network adapter that is used by Windows to access the Internet.
- Inside Windows, create a Gateway/NAT. Here's how: http://technet.microsoft.com/en-us/library/dd469812.aspx (ignore the DHCP part, that's overkill)
Now you have all ingredients to reach the VPN from OS X. So imagine this scenario: the VPN allows you to access some private IPs, say 172.16.123.0/24
. You need to tell how OS X can reach 172.16.123.0/24
via 192.168.12.34
:
route -n add 172.16.123.0/24 192.168.12.34
Read here how to make that permanent: http://blog.irrashai.com/blog/2009/03/how-to-add-static-route-in-mac-os-x/
To troubleshoot and work through this ifconfig
(not to change anything, just read the output), man route
, route
and ping
are your friends. ;)
