Having trouble getting the LANSuite 2003 firewall to work and am about at the point or giving up and installing a third party firewall which would be a shame as the whole point of our using LANSuite was that it was an integrated solution.
Here's what I've got. All suggestions welcome.
---
THE LANSUITE SERVER SETUP
Windows 2000 (workstation)
1 NIC (internal interface)
1 external modem.
THE PROBLEM
Any firewall settings of medium or above causes the server to become isolated from the rest of the network.
Attempting to browse the workgroup produces the error
“The list of servers for this workgroup is unavailable”
Attempting to browse a shared folder produces the error
“There are no logon servers available to service the logon request”
Setting the firewall security to low works but extremely slowly--too slow to be useful really and the low setting does not provide the desired level of security anyway.
ATTEMPTED SOLUTIONS
Things I’ve tried which didn’t work... Mostly based on posts in these forums from other people's similar problems.
Adding extra permission sets to allow local network access and file sharing.
Enabling the NetBEUI protocol.
Neither of these worked so were removed again for troubleshooting purposes.

Choosing 'High' security is your best option to start. This is the only default rule that specifies 'internal to this computer' and 'this computer to internal' rules.
You will then need to add The 'Windows sharing' rule and everything should work as expected.
Personally I would copy the default 'High' rules and replace all the 'this computer to internal' & 'Internal to this computer' rules with 2 rules that simply allow all protocols between the server and internal network. This will still leave you with 'High' internet security but no internal restrictions.
