kerio 2.1.5 UDP datagrams ?

B

Bloned

Just installed Kerio 2.1.5
Some applications don't just want to connect to the internet, but also want
to send UDP datagrams. Can anyone tell me what these are and if I should
allow those in Kerio ?
And I was wondering, is Kerio 2.1.5 the same thing as Tiny Personal
Firewall ?
TIA

Thanks for the link Tiger, I'm sure it's very good, but I'm afraid
my lack of technical know-how is catching up with me, in other
words: huh? For now I decided to deny the UDP-datagram sending,
and everything still seems to work properly, so I'll just stick
with that untill I've upgraded my brain.

I should have indicated that you need to scroll to the bottom of the
site and check out the chart. It will tell you what typically uses udp
packets. Unless you're into file sharing, running on a network, or
watching or listening to streaming media, you're probably good to go
with denying udp.

Now this I understand. And you shouldn't have indicated to me to scroll
down, I should have taken a better look at the site instead of closing it
after getting scared after the first sentence.
Thanks for your help.

This list is not complete, and at least one *important* reason for outgoing
& incoming UDP packets that's not mentioned is DHCP. That's how most
people get their IP address from their ISP. And without an IP address no
surfing, no mail, no usenet, ... no internet. :-/

And disabling all UDP traffic will stop DNS lookups from working, so you
won't be able to go anywhere or see anything..

has rulesets you can download and import into Kerio

they are very thorough, but block a lot of ad sites and spyware sites
too
