Sharing Itunes library over Wireless Network

I am attempting to share an Itunes Library using Itunes 9.0 Home Sharing feature.  I am able to see the libraries on the wired LAN but not the wireless.  I have both PC's on the same workgroup but the wireless subnet is a different IP address range.  I am using a Sonicwall TZ180 router /firewall and the rules allow all traffic between the WLAN and LAN and vice-versa.  I am also allowing Netbios broadcasts through as well.  I can ping the Itunes PC from the wireless laptop and I can see shares on the same machine no problem.  The itunes PC can also do the same.   After running a Wireshark sniff I noticed there were a few errors that might be related.  They are SMB and SMB2 errors for NTLMSSP challenge response.  Any thoughts?
