NetBios Broadcast over IPSec tunnels

Hi everyone!

I have 3 subnets, that connected by IPSec tunnels.
The goal is to connect to the MS-DOS station in the subnet2 from subnet1 by using NetBIOS other TCP. MS-DOS station is configurated to use TCP/IP protocol.
MS-DOS station IP in subnet2 is 192.168.143.43

There are:
subnet1 192.168.119.0/24
Gateway Linksys router - 192.168.119.254
subnet2 192.168.143.0/24
Gateway Mikrotik router 192,168,143,254
subnet3 192.168.118.0/24
Gateway Linksys 192.168.118.254

There are IPSec tunnels between subnets, as described below:
subnet1 – IPSEC - subnet2
subnet1 - IPSEC - subnet3

On the Linksys routers is setup to enable NetBIOS broadcast
From subnet 1 to subnet 3, there I use Linksys routers, and there is enable NetBIOS broadcast. I can connect, resolve the NetBIOS name and map network drive of remote MS-DOS Station.

But from subnet1 to subnet2, I cannot connect to the remote MS-DOS station.
Please help to configure Mikrotik router to enable NetBIOS broadcast and solve this problem.

I do not know the function of Linksys “enable broadcast”, but MikroTik RouterOS does not have one button that allows broadcast frames to send into IPSec tunnel.

I can imagine about EoIP+IPSec to get broadcast through, but EoIP configuration is required on both ends, and Linksys does not support such protocol.

Thanks for replay. Ок, I’ll change my Linksys to another MikroTik router. How can I configure EoIP+IPSec on the two microtik routers to get NetBios broadcast in the local and remote networks?

No such thing in Router OS. For really old Windows networks, use WINS, else setup Active Directory servers.

JJCinAZ, thanks for replay, but please do not flood in the topic, I need to realize Netbios Broadcast. If I want to configurate Active Directory or Wins Service, I am sure you will return to. I want to say again I need to enable Netbios broadtsast over TCP/IP in the IPSec tunnel, and not the old Microsoft protocol Netbeui.

Aren’t you rude. He’s right use WINS. As for EoIP with IPSec, its in the wiki.

cbrow, thanks for replay. Sorry for my rough English.

How WINS will help me with mapping network Drives and remote management the MS-DOS station? Instead WINS I can use an entry in the Host file.

Could you give me the link.

Then once you have your IPSec established create your EoIP tunnel using the ips on the ends of the tunnel. I didn’t see a wiki page to set this up. If I get time in the next couple days I’ll write one up and put it on my site.

“Enable broadcast” also have Dlink and Zyxel routers.

Subject is still very relevant.
