Does anyone have a work around for Outlook and Windows File & Print services through a NAT gateway in a Win2K and XP environment with Active Directory? We have a situation where we do have to pass this kind of traffic through such a gateway and it breaks. We see the client send SAM LOGON requests on netbios datagram service 138/udp. I would guess the client is registering but I'm not sure. The problem is that the netbios header contains the source IP address. Once we NAT, this does not match the IP header IP address. We see the packets arriving at the AD controller with the NAT address but we see the replies being sent to the original address (the one in the NetBIOS header). It appears there is no nat helper for netbios dgm although there is the start of one at http://suif.stanford.edu/~csapuntz/ip_nat_netbios.c - in fact, if no one has a work around, we might be interested in sponsoring someone to finish and submit this patch. Please let me know if you are interested. Has anyone gotten such a set up to work? Perhaps there is a way to manipulate the behavior of Outlook and Windows to get the information via a different protocol? Thanks - John -- John A.
