Allow NetBIOS so WINS works.

CarlosNaldinho over 9 years ago

I'm trying to get cross-subnet windows browsing working and I am quite close.

11:48:46

Default DROP

TCP

192.168.2.200

→

192.168.2.100

139

[SYN]

len=60

ttl=64

tos=0x00

srcmac=52:54:00:c8:71:58

dstmac=f4:f2:6d:06:59:6b

I noticed this and I think it might be the last piece of the puzzle. 192.168.2.200 is the Ubuntu VM that is running SAMBA which is acting as my WINS server.. 192.168.2.100 is my Sophos UTM. Port 139 is the port used by NetBIOS Session Service.

How do I add a rule so that this communication is not dropped?

Figured I might as well ask a second related question -- is there anything else that could be blocking the proper functioning of WINS?

I have a WINS server set up at 192.168.2.200 and a Local Master at 10.1.1.200 with 10.1.1.0/24 using 192.168.2.200 as the WINS server. Both subnets are connected by Sophos UTM established IPsec site-to-site VPN.

Name resolution works on both subnets but actual network browsing from Windows only works for 10.1.1.0/24

Assuming that my question above is not the issue can someone give me any idea of what rules I need to get what I'm trying to setup to work?
