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

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
