Why won't packets destined for port 445 transverse the VPN?

Linux (OpenSWAN) <-> Sonicwall VPN.  All other services are accessible on all machines through the VPN, however, when trying to connect to a Windows share across the VPN this error comes up:

"\\10.10.12.244 is not accessible. You might not have permission to use this network resource.  Contact the administrator of this server to find out if you have access permissions.

There are currently no logon servers available to service the logon request."

I don't know why your configuration does not work, but do note that accessing windows share "\\10.10.12.244" can use port 139 (netBIOS over TCP) instead of port 445 (SMB over TCP). Additionally routers/firewalls could be configured to block netBIOS/SMB traffic.

Are you having problems accessing a single machine or all machines? What is the server and client OS that you are testing?

Both sides of the firewalls are set to allow all traffic coming from the source IP range of either side of the VPN.

This is what I've tried:
Machine on right (WinXP Pro)->Machine on left (WinXP Pro) using \\10.1.1.23 "The network path was not found."
Machine on right (WinXP Pro)->Machine on left (Linux sever with samba) \\10.1.1.1 "\\10.1.1.1 is not accessible.  You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.  The network path was not found."
Machine on left (WinXP Pro)->Machine on right (Server 2003) \\10.10.12.244 WORKS.

The left side is a Linux server and the right side is the Sonicwall.  So I guess the only issue is when trying to find stuff back on the Linux side from the Sonicwall side...

And pinging from right (WinXP Pro) works for machine 10.1.1.23?
