There may be, but I don't run linux so I don't know if there are for redhat.
If you are just talking about share level access then that work's over NAT.
Logging on to a domain is where the problem is.  You logon, but the windows
client gets confused due to payload in the packet.  Its a pretty complex
issue unless you're someone who understands the netbios protocol.  I started
reading RFC 1001 and 1002.  There may be easier ways or you may not be
trying to do what I think you're doing, so hopefully someone else can help
you better than I can.
