Fujitsu Lifebook P727 laptop review
I have been using Zone Alarm (freeware version) for 2 years on my Windows 2000 Server, but after loads of problems with it (interfering with DHCP/DNS and causing all sorts) I had been considering a change. The final straw was when I downloaded the latest update and it said:
"This Zone Labs product is not intended to protect server operating systems. This may affect our ability to support you. Do you want to proceed with installation?".
I would have clicked Yes, but I thought that if it now detects my OS, it will probably prevent me from receiving future updates anyway.
I realise that the freeware version was never intended for servers anyway, but it has been protecting my network for 2 years - maybe too well!
Obviously I am going to need a good firewall, preferably free or at least very cheap (or dare I say it downloadable and update-able without me having to pay for it until I've tried it - without it being a trial version that probably won't update).
Thanks MichelleC - I'll give it a try.
One thing though - I'm assuming I'll need to get ZoneAlarm off before installing Kerio. I can download it still using ZoneAlarm, but there's going to be a long time where I am connected to the net without a firewall, unless it'd be OK for me to switch off my net connection while it's uninstalling & installing the new one.
I remember when I did ZoneAlarm it wouldn't let me connect to the net and the only way around it was to install with the internet connection on, but this meant I got a virus!
Anyway I'll try and sort something out - just wondering if you knew if it'd allow me to have my net connection off!
Disconnect from net and once ZA is uninstalled it's best to reboot 1st then install Kerio. When it's guard comes up I click ok's and let it do it's own filtering. It'll ask ok for all progs traffic.
Is this version 2 or 4? I've just looked at the comparison chart and it says version 2 runs on a Windows server OS but has been discontinued, and both version 4 (free and full versions) don't run on a Windows server OS. Whether this is strictly true or whether it's just like ZoneAlarm was (i.e. it will still work) I don't know.
Are you running W2K server?
Tried installing Kerio but it won't install on W2K server, which is unfortunate. Anyway, thanks for the suggestion MichelleC.
Anyone know of another firewall - free or otherwise - that I can use?
I would recomend a hardware device for a network, that way you will be protected from the public domain without interfering with normal network communication , for DHCP and DNS to function you will need to open port 53 88 and 89 on ZA (if your using a version that gives you that level of control) ... I use Vigor 2600 devices.. adsl router, good price / vpn endpoint and passthrough.
I had considered a hardware firewall, and it did cross my mind that I could build one and have a separate web server and primary domain controller, but I think, for now certainly, I'll stick with a software firewall.
As for opening ports, I'll have a look in ZoneAlarm and see if there's any way I can do that.
What I have just done in ZA is run the network without the internet connection on and just allowed everything that came up, which is basically what I did last time.
Anyway, thanks for your suggestions and I'll let you know what happens in the next few minutes.
It seems that ZoneAlarm, or at least the free version I have, does not allow me to open ports manually. It has allowed connections for port 53 but I can't see any mention of the other ports you mentioned.
I'm going to leave it overnight and see if it blocks any more; there are a few DNS things that have been blocked but this might have been before I checked the box to allow DNS/DHCP on the trusted zones.
I also have the option to allow DNS/DHCP on internet zones, but wasn't sure if this was a good idea so I left it.
The outcome so far is that IF I can get ZoneAlarm to behave itself and only block what it's supposed to I might stick with it as it still WORKS on W2K server.
Loads of info here,I was looking for a page I viewed recently with a huge list of firewalls,all d/l and including a review of each,but couldn't find the page(Its been bookmarked but cannot find it now as I have several browsers)
Thanks for that link Chegs ®.
At the moment I've not found anything though...
The problem with most of them is that if they are personal firewalls they won't work on 2K server. Norton won't work I don't think - it might but there's probably a Symantec firewall for that, like there is with Norton/Symantec Ghost.
