I presume you mean "Outpost". This is no firewall, neither does it create
any useful information. Why do you even log such stuff?

In case of doubt: no. Why are you even asking? If this answer isn't already
clear to you, you should not try to run any firewall.

And what's the meaning of "SYTEK" in that context?

Yes, Outpost 4.0

I was looking for description UDP:500 and I read in this way: 500 SYTEK
UDP
Unfortunately, I don't know what the "SYTEK" means

Who tells such a nonsense? UDP 500 typically is ISAKMP, which is exactly
what /etc/services tells. I'm not able to find anything there about
"SYTEK".

And as someone who wants to run a firewall you should definitely know that.

As Sebastian said in his first reply to you:
When in doubt - NO!

If you're having VPN users that can connect to your network while
travelling you might need to open this port in order to get IKE working.
