Downloading and Installing Sygate Personal Firewall
Sygate Personal Firewall may be obtained from: http://smb.sygate.com/products/spf_standard.htm
To start downloading, simply click the Download Now image.
Installing the product is like installing many Windows Programs. Click the "Setup" button, and then simply follow the instructions!
If it asks you to restart, you must do so, otherwise you are not yet protected.
After Installation there should not be anything to do, the firewall will automatically start in normal mode.
- Block All - Everything will be blocked.
- Normal - Rules will be followed, and it will always prompt if it isn't sure.
- Allow All - Dangerous mode, nothing is stopped, in or out, rules are ignored.
Of those modes, you should nearly always run Normal, and if you think you're under some sort of attack, choose block all to be safe while you see what could be wrong. See Configuring below to learn how to choose another mode if you need to.
The firewall currently has no rules, basically everything is blocked unless you permit, and it will do this by asking questions. The first thing you might do now is open Internet Explorer, you should be confronted by a screen such as below:
What you see is something like I discussed above. This is safe to allow. You have 2 options: Yes and No. You can also tick the box, if ticked, this choice sticks for all future times Internet Explorer tries to make contact with the world. This is the four options, Yes (not ticked), Yes always (ticked) and so on.
If you tick the box, Sygate will build its rule which allows/denys this application to access every time in the future. If you just tick Yes or No, it will only apply this time, and the next time it will ask again.
What happens if you tick the box and then click NO by mistake, but you really meant yes?
What happens if you ticked the box and clicked YES but you didn't mean to?
Configuring Sygate's Rules
Quick access to options can be obtained by right clicking the Sygate icon, the two arrows.
The first option, in Bold, opens the main control panel.
The next three choose the mode. The one that is ticked is how Sygate will currently treat traffic.
The rest allow you to edit Options, we are interested in the Applications one, which lets us edit the rules.
The rules Sygate has made are based on Application. From the right click menu, choose Applications...
You will see a list of applications. Find the one you want to change, i.e. the one you made a mistake on. There is a little square box to the left of it. Three symbols:
- ? - Ask.
- X - Deny.
- ticked - Allow.
The third column "Access" echoes the access permitted in English form.
Advanced users may select an application and click "Advanced" to permit which ports this application may access, and servers etc...
Unfortunately the default may let the application access any port, this should not be a problem for legitimate applications.
From the right click menu, Select Advanced Rules.
From here, you can make your own advanced rules, you will see them in terms of boxes and symbols, as well as structured English.
It is beyond the scope of this site to explain advanced rules or the full workings of the firewall. You will find this in the help files, on Sygate's site, and other sources. Only more advanced users will ever find these helpful, the average Home user will now be sufficiently protected.
