Hello,

1. Create an URL Group for the websites that you want to block.
2. Create a HTTP Policy for that URL Group to block and make sure that rule is the first rule at HTTP Policy order.

And please read documentation here:

Hi, Everybody !

Sorry KursadOlmez

That rule does not work for HTTPS sites because http port is 80, https port is 8080.
HTTP Policy's rules does not check to 8080 port number.

for example;
for http address is working but https address opens

That is a problem for all of us, There is a solution for this problem: target site's ip address.

Create an IP Address Groups for block Ip address
Add a new rule in the Traffic Policy and block that new IP address group

Probably that port will stop working but you can try...

Ip block will work Smile

@Goran,
do you mean set traffic rule that block specific port? if yes then since they use usual HTTPS port, it will block any https site. or you have different mean? please let me know. thanks bfore

block ip address also not effective choice, since the site use many ip (I think they use dynamic public IP). thanks

I tried everything. Protocol Inspector is checking to real or fake pakets .
no_name didn't wanted to it.

@no_name
yes, block ip address also not effective choice but There isn't better a solition
if Kerio makes HTTP Policy like-tab HTTPS Policy tab, will be very well
for now, three methods can try;
1. target site's ip address block.
2. service HTTPS remove in the Traffic Policy (default from Nat) and only request HTTPS sites allow on the second nat
3. if web filter use relate groups block but relating on the groups all sites's is block.

no need to set any special rule

as default kerio sets trusted/local to internet interfaces https, http,ftp etc... just set to http only so your clients can access only http based on http rules. And if you have such clients need to access https just make a new rule set what ever user as source to internet interfaces use service http, https or what ever.

I hope it helps.

I mean you can add HTTP inspector to HTTPS protocol...
I newer try that, but maybe will work...
When you do that and your HTTPS work normaly... You can i rules put forbid for whatever site and that will inlcude HTTPS and HTTP protocol's
But i think it will not work, but you can try...

Yes, you can create time range,
in Traffic you forbid HTTPS, but in that time range.
IF you don't see time range in traffic rules enable that column.

you cannot block https addresses like http but you can block by user. Use firewall trafic rules to do that.
