Subject: TIS fwtk vs. NT SMB shares

We've successfully firewalled an NT fileserver using the TIS firewall
toolkit, v2.0 plug-gw on port 139.  The problem is only Unix clients can
access these shares/filesystems (using samba), Win95 clients cannot. 
 
Because the NT server checks the servername as well as sharename of each
query we've edited the local LMHOSTS files so that the NT servername is
mapped to the firewall's IP address.  However, although we see traffic
going to and from the NT server, all our Win95 clients fail to mount the
share.
 
Are there any white papers on firewalling NT SMB filesystems?
