How can I configure my networking to allow my Host OS (10..10) to network with my Guest OS (XP)? My Host OS is assigned a private IP from my router (192.168.1.103), and my guest OS is using a Parallels-assigned IP of 10.211.55.3. I performed a 'straight' install of Parallels and am currently at Build 5160. My Guest OS can ping my Host OS's IP address but not the other way around. How can I configure Parallels to allow this? I am running a test lab of Notes/Domino and want to set it up so my Notes Mac client can connect to Domino running on my XP guest OS. Any help would be greatly appreciated.
