How to block Lantastic network between MT bridge?

Thu Aug 03, 2006 10:38 am

Hi,
I've connected two sites using MT wireless bridge. All two sites have mixed network, IP and Lantastic based. The Lantastic are used for connect Cash machines to the server (cash machines can use ONLY Lantastic) and the servers of the two sites are connected to a central server via IP (using bridge). This is the problem: the cash machine of the two sites have the same name (es. cash 1, cash2 etc.) and this creates a conflict in lantastic network... I cannot change names to the cash machines.
There is a mode for block lantastic network between MT routers?

Not sure about the lantastic, but looking at it from reverese, why not only allow ip (or only tcp/udp/icmp) to pass through the bridge?

Should have the same affect

This is the solution for my problem:

[tivuesse@Ponte Grotte Castro 1] > ip firewall filter
[tivuesse@Ponte Grotte Castro 1] ip firewall filter> print
Flags: X - disabled, I - invalid, D - dynamic
0 chain=forward in-interface=ether1 protocol=tcp dst-port=137 action=drop

1 chain=forward in-interface=ether1 protocol=udp dst-port=137 action=drop

2 chain=forward in-interface=ether1 protocol=tcp dst-port=138 action=drop

3 chain=forward in-interface=ether1 protocol=udp dst-port=138 action=drop

4 chain=forward in-interface=ether1 protocol=tcp dst-port=139 action=drop

5 chain=forward in-interface=ether1 protocol=udp dst-port=139 action=drop


Lantastic network use 137,138 and 139 ports, I've blocked its for TCP and UTP protocols and all it's OK!

Thank You, Savage, I've tried this way after your post.
