Question

Kaspersky blocks traffic from Cisco SSL VPN online portal

Asked by: Craig_Campbell

Recently our company had an upgrade to our external mail client, which runs through an internet browser to a Cisco SSL VPN Portal.  However, when I try to run it on my home PC something blocks all pages after the initial login screen.

After disabling Kaspersky Internet Security 2009, i tested the client and it worked. I have tried to disable certain features individually to eliminate the cause, but it only works when I fully disable the security protection.

Has anyone seen an issue like this before. Is there an area where I have to allow all traffic from the portal address?

OS: XP SP3
Browser: Internet Explorer 8 (firefox not supported)
Kasperksy Internet Security: Ver 8.0.0.506

Thanks in advance

try adding the website portal to Trusted zone in IE

Thanks Admin3k,

Already tried that, along with other settings in IE but to no avail. I am pretty confident it is a Kaspersky issue.

 

by: Admin3kPosted on 2009-06-16 at 01:40:22ID: 24635957

if you are using Cisco VPN client , there is a firewall that may be enabled, if you could right click the Tray icon & check if it is enabled or not.

also try disabling the web traffic ocmpoent or at least the HTTP traffic analyzer function as shown in this post under the General>web traffic settings

Its not the Cisco VPN Client, its a web page portal that the user connects to and it establishes a secure connection from the remote PC to the VPC concentrator (ie. there are no installers needed).

Just tried disabling HTTP traffic analyzer, but it did not work.

Really strange, because as soon as I pause Kaspersky's protection it works. As soon as I resume protection, it blocks the page. Would there be a reason that Kaspersky is blocking Java RTE from running? I can not find anything that is relevant, or that works.

Found the fix for this issue. Admin3k was on the right track, and it was to do with http filtering, but it had to be configured through the firewall ports for https SSL connections and not through the general KIS 2009  settings for HTTP traffic.

Thanks for your help Admin3k.
