A few questions (noob)

Hi all.

So i decided to try out L'n'S and untill now i'm very pleased (nonbloatware + low mem foot print = win :> ).

However, i come from an application based Firewall,
but i'm starting to figure out how to make rules.
But i'm interested in what the apps are allowed to do,
when i dont make a rule for them?
F.e i just authorized firefox to access the internet, but didnt make a rule.
does that mean that it's allowed to use all ports or is L'n'S "smart" enough to only allow TCP port 80?

Second, i've made 2 rules for my bittorrent client :

TCP allow port 52001 in/out
UDP allow port 6881 in/out

Still i see many connections to the 52001 port being blocked in the log?
I've placed these rules just above the TCP block incomming connections rule (advanced ruleset).

Btw. is there a certain tip for how i place my rules (top/bottom)?
iirc p2p needs to go just above the TCP block incomming connections,
so what about games/browsers/ftp aso.

 

If you authorize an app but didn't make a rule LnS will allow the app to communicate on all ports and to all IP addresses. This can easily be changed by double-clicking the app in the list and entering the ports/IP's you want to allow/dis-allow for this app.

Re. 52001 port being blocked. What rule is blocking it ?

 

The "TCP: Block incomming Connections" rule.

i've placed my bittorrent rules just above it.
