I like sysgate very very user friendly as far as zone alarm i hate the resources it takes up. This forum and another site i help on i could shwo time after time the promblems with zone alarm , same goes with mccaffee and norton.
Outpust never used it yet i 've been meaning to try it out heard alot of good things, for example my one friend zone alrm took a dump on him, he tried sygate it gave him some werid resaults with using mirc he tried outpost and loved it.
MSN Messenger i foun this about the ports it does say disable firewall when using msn.
(Watch Out! Opens a wide port range!)
NOTE: Shut off any personal firewall programs such as BlackIce, ZoneAlarm, etc.
Ports 6891-6900 enable File send,
Port 6901 is for voice communications
Allows Voice, PC to Phone, Messages, and Full File transfer capabilities.
