I have had that configuration running for ~2 years without any issue.
I run a Juniper VPN client on the MacOS host (SL 10.6.8) and several XP guests on Parallels 6. The XP guests have always had "pass-thru" access of the VPN connection.
I have now built a Win7 64 guest that is unable to access the VPN connectivity the way that the XP vm's can.
I'm thinking that I might need to update to the latest version of Parallels 6 and give it another go as I can't find any shared network settings that have any impact on the situation.
