Re: netbios over internet [7:40784]
NetBIOS is a session-layer protocol and API. Of course, it is able to be routed (routable), just as RPC and NFS and TCP and UDP are also routable, as are HTTP, FTP, etc. In comparison, LLC, is a data-link-layer protocol. It is not routable without some major shenanigans. NetBEUI resides right on top of LLC and doesn't make any calls to a network layer. Also, NetBEUI does all its own reliability, etc. It doesn't rely on TCP, for example. NetBEUI handles all of the communication work relative to NetBIOS. This is different from the other implementations of NetBIOS. NetBIOS refers to the programming interface in all implementations. In the NetBIOS/TCP environment, it also refers to the portion of the packet that carries NetBIOS commands, replies, and data. In the NetBIOS/NetBEUI environment, NetBIOS refers only to the API, and NetBEUI refers to the protocol. In the NetBIOS/IPX environment, NetBIOS refers to both the API and to the protocol. To understand the details of terminology use, it's worthwhile to examine the three different frame structures for TCP, NetBEUI, and IPX.

RE: netbios over internet [7:40784]
I disagree that most ISP's block the following:
tcp or udp 135 (mapping)
tcp or udp 137 (NetBIOS Name Service)
udp 138 (NetBIOS datagrams - the actual data)
tcp 139 (NetBIOS Session)
Any more than they block the rest of it. If they did, for one thing, your
firewalls wouldn't be blocking this stuff every minute as the script kiddies
aim their pre-written tools at massive netblocks. Furthermore they would
have to state this in their service agreements. I can tell you for a fact
that Sprint, XO, New Edge (who bought @Work), MCI/UUNET, PSI, QWEST, and
AT&T (not including the cable modem market - that is another story) do not
block this traffic from/to customer networks.
Cable providers do have a nasty habit of blocking udp 500 (isakmp) but that
is for financial reasons (they want you to pay for "business class" service
if you use a VPN.)
That doesn't mean that they don't block it (NetBIOS) from their own servers,
as most sane people would/should/do - but if they blocked their customers,
however foolish, from doing this they would be violating service agreements.

The biggest obstacle is the fact that most ISP's filter NBT traffic. It
works just fine over a VPN connection, as the ISP doesn't see the NBT
packets; they see VPN traffic. Basically all you have to do is get around an
access list blocking ports 137, 138, and 139.

I don't think it can.
As far as I know, it can do IP/IPX/DecNet/AppleTalk/Vines/CLNS.
NetBios over TCP/IP will work with GRE but not straight NetBios or SNA.
If GRE works with NetBios or SNA, it will be cool.
I think that is why we use DLSW with NetBios and SNA connection.

RE: netbios over internet [7:40784]
All you have to do to do NetBIOS over the internet is either use WINS or reference the share by IP address, assuming you are using either NT or Win2K. For instance, from a command prompt: net use X: \\123.123.123.123\C$ /user:ntdomain\ntusername Thththththats all folks.

Re: netbios over internet [7:40784]
This thread has been taken out of context. The real initial question was whether or not you could bridge over the internet. E.g., have 2 LANs that are Layer 2 Bridged over the internet. Somewhat like DLSw+ can do for NetBIOS and SNA. It would have the same effect as doing this: (which you can't do) int tunnel0 tun sour 10.10.10.1 tun dest 10.20.20.1 bridge-group 1 int eth0 bridge-group 1 Somehow IP would have to encapsulate the incoming MAC frame as the data portion of the packet, and then release it as an ethernet frame on the other end.

Re: netbios over internet [7:40784]
You can use NetBIOS over TCP/IP (using some kind of encryption if you choose), or if you have Cisco routers at either end connected to the internet, you can use DLSw+ to form peers between those two routers to tunnel the NetBIOS across any IP network (LAN/WAN, etc) which allows Layer 2 acknowledgements to be preserved (you may need to tweak the NetBIOS timers in DLSw+ if there is alot of latency over the internet between the two DLSw+ peers).
