[PLUG] Ports needed to use Samba or MS networking functions

[Jesse Huestis <jhuestis@comcast.net>]

Hi:

I have a situation where I am trying to limit the exposier of a LAN to 
attacks from a wireless network.  What I have done is to issolate teh 
wireless side giving it only internet access and blocking all other 
traffic.  They need to connect to a Network and Printer share on the LAN 
side from the wireless network.  

Solutions

1) Put all computers on the same subnet, but this opens servers etc., to 
attacks if someone hacks the wireless network.

2) Open up the ports to make the connections and limit the routing to 
just the IP addresses IP have assigned and to the times I have 
designated using the firewall.

I like solution 2 because to adds serveral layers to get around, I am 
having trouble identifying all the ports I need.  Right now I have found 
133-139 as some of the ports necessary, I think.  It did not work when I 
opened just those.

Thanks,

Jesse
