These are my own observations on how to configure Sygate personal firewall for internet connection sharing
The first thing we are going to do is to disable file and printer sharing over the internet. Open Sygate Personal Firewall, go to the Tools->Options menu and click the [Network Neighborhood] tab. Select each "Network Interface" from the combobox in turn and untick both checkboxes in the "Network Neighborhood Settings" box.
Note: You may wish to turn them on for a specific network card, your home network for example.
Once this is done, click the OK button to close the window.

Name
Path
Generic host process for Win32 services
C:\Windows\System32\svchost.exe
Internet information services
C:\Windows\System32\inetsrv\inetinfo.exe
Message queuing service
C:\Windows\System32\mqsvc.exe
MS DTC console program
C:\Windows\System32\msdtc.exe
NDIS user mode I/O driver
C:\Windows\System32\drivers\ndisuio.sys
NT kernel & system
C:\Windows\System32\ntoskrnl.exe
TCP/IP services application
C:\Windows\System32\tvpsvcs.exe
Now find the application named "LSA Shell" in the list, right-click this item in the list and select "Advanced...". Untick the "Act as server" checkbox and then click OK to close the window. Repeat this step for "Application layer gateway". Again click OK to close the application list.
Finally we are going to allow the local network machine to share the internet connection. Go to the Tools->Advanced Rules menu option. On the next window click the Add button.
- In the "Rule Description" box type "Internet connection sharing"....
