(Resolved) ShrewSoft VPN Proxy Services Blocks DNS Requests for VMWare Workstation Guests

Filed under: Open Source,VMWare,Windows 7 — J. Abram barneck @ 6:00 am

UPDATE: 3/5/2010
2.1.6 beta 6 addresses this issue, so please install this version and ignore the rest of the comments below.

Ok, so I am big support of ShrewSoft VPN Client and I am also a user of VMWare Workstation. However, I have found an incompatibility between the two.

I tell everyone here at work to use ShrewSoft VPN Client on their Windows 7 64 bit clients. However, they are all running VMWare as well. So I feel it is my responsibility to also inform them of this issue that was found by one of my coworkers.

Well, a strange problem is seen on VMWare Guests running on a host with ShrewSoft VPN Client installed. No DNS requests are going out for the Guest. A DNS Request never leaves the host.

I seached the following term on the VMWare forums: DNS Bridged

The following VMWare Community discussion appeared:
DNS Name Resolution using a bridged network connection not working

If you stop the ShrewSoft DNS Proxy Daemon, then the issue goes away.

Also, this is not really a reason to stop using ShrewSoft VPN. There is a post about Cisco’s VPN Client firewall causing the same issue.
