Network Broadband security advice please

  bigchasbroon 16:43 07 Dec 2004

I have 4 pcs netwroked and will shortly be installing broadband. I have a Netgear DG834G router which provides NAT and SPI firewall. Do I need firewall software on each of the PCs or does the router provide sufficient protetction. Obvioudsly I will have AV on each machine.

Thank you in advance

I have 3 pc's networked on bb and have always used ZoneAlarm (free edition) on all machines,I have my router firewall disabled mainly due to its 3 settings which seem to be "all or nothing" I do not rely on xp's firewall as it does not check outbound traffic (SP2 firewall is just as useless on this score despite the hipe!!) I have had no problems at all in 4 years running things this way.Hope this helps.

Software firewall is only necessary if you want to also have outbound protection. The firewall in the netgear kit is inbound only. My own view is that it is not necessary to run a software firewall unless you are in th habit of:
1. Opening each and every email attachment that comes your way.
2. Not running a good updated AV
3. Not deleting unknown emails, but opening them "just to see"
4. Visiting sites that plant nasty stuff on your PC. Yes I know this can happen without one being a porn site regular, but the best protection from virii and other malware such as trojans etc is EXTREME CAUTION
5. With a BB connection, any dialler that does get onto your PC can't go anywhere if you leave the old dial up modem cable disconnected until you need it because BB goes down (very rare)

So, no, I wouldn't bother with a software firewall.

BTW my router is a netgear and it's firewall (NAT & SPI) does a good job without getting in the way of anything I want to do. I cannot see the point in using up PC resources and other potential problems with Z A Pro, so I don't use it any more.

thank you gents, I think that I might just go with the router and see what happens. I have been on ISDN for a few years with a router. Only providing NAT protection and I havent had any problems. I also keep up-to-date AV software.
