2.3 Installation
Conflicting Applications and System Services
The WinRoute installation program detects applications and system services that might
conflict with the WinRoute Firewall Engine.
1.Windows Firewall’s system components1 and Internet Connection Sharing.
These components provide the same
Windows Firewall / Internet Connection Sharing system service.2.
Warning: To provide proper functionality of WinRoute, it is necessary that the In- ternet Connection Firewall / Internet Connection Sharing detection is stopped and forbidden!
2.Universal Plug and Play Device Host and SSDP Discovery Service
The services support UPnP (Universal Plug and Play) in the Windows XP and Server 2003 operating systems. However, these services collide with the UPnP support in WinRoute (refer to chapter 16.3).
The WinRoute installation includes a dialog where it is possible to disable colliding sys- tem services.
By default, the WinRoute installation disables all the colliding services listed. Under usual circumstances, it is not necessary to change these settings. Generally, the following rules are applied:
•The Windows Firewall / Internet Connection Sharing (ICS) service should be disabled. Otherwise, WinRoute will not work correctly. The option is a certain kind of warning which informs users that the service is running and that it should be disabled.
•To enable support for the UPnP protocol in WinRoute (see chapter 16.3), it is neces- sary to disable also services Universal Plug and Play Device Host and SSDP Discovery Service.
•If you do not plan to use support for UPnP in WinRoute, it is not necessary to disable the Universal Plug and Play Device Host and SSDP Discovery Serviceservices.
Notes:
1.Upon each startup, WinRoute detects automatically whether the Windows Firewall / Internet Connection Sharing is running. If it is, WinRoute stops it and makes a record
1In Windows XP Service Pack 1 and older versions, the integrated firewall is called Internet Connection Firewall
2 In the older Windows versions listed above, the service is called Internet Connection Firewall / Internet Con- nection Sharing.
