I am running Parallels 4 with RHEL 5 32-bit as my guest OS. I have a corporate VPN running on the host Mac OS X and am attempting to get the host OS to see the VPN network. My Network Adapter is in "Shared" mode. The problem seems to be DNS. If I resolve the IP address in the host OS and use the numeric address in the guest OS, then things like ssh work fine. However, if I use the symbolic/string name (with ping or ssh for example), then things do not work.

may be this will help: quote from http://forum.parallels.com/showpost.php?p=377338&postcount=2 "About problems with dns.. there is an issue in the current Parallels Desktop with DNS and VPN. It can be workarounded: it is required to manually add the DNS-server for VPN-related sites to the Network Connection. Please try to go to the Control Panel -> Network Connections, right-click proper connection (most likely there is the only one 'Local Area Connection') and choose properties, then select TCP/IP -> Properties and select manual configuration for DNS ("Use the following DNS server addresses). Make your preffered DNS server be your corporate dns-server. As Alternate - enter "10.211.55.1". If you don't know your corporate DNS-server, run the Mac-terminal (/Application/Utilities/Terminal) and enter the next command "sudo scutil --dns". This (assuming that VPN sites are accessible from Mac) should output list of DNS-servers." So, steps to workaround this on linux might be 1. do "scutil --dns" on mac and determine VPN's dns server 2. edit /etc/resolver.conf on linux and either add (I don't know details of RHEL DNS Resolver implementation, so don't know whether it is possible to add second dns-server) VPNs dns-server before 10.211.55.1, or replace 10.211.55.1 with your dns-server. I've heard some rumors that some linux-users have two resolv.conf and do switching between them manually # vim /etc/resolv.conf
