PC Tools Firewall?

Hello Hipgnosis,

Most firewalls will use an SPI (Stateful packet inspection) which would allow the returned packets from an outbound connection. Or at the minimal, have filtering in place to stop the possibilty of inbound connections being allowed via outbound connections. There is also the possible problem of receiving invalid TCP packets which can, at times, cause problems for the TCP/IP
Example:

 

Ok, I get it; the SYN/FIN is probing for open ports. Thanks for the clarification.

 

Hi Hipgnosis,

Scans for open port are normally made by "SYN" scans. A "SYN" packet is sent, if a "SYN/ACK" is returned, then that port is open and allowing inbound connections (also known as a "Half open scan")

some info

 

is it good...

 

I'm going to give it a try too, it supports vista.

Edit: No vista 64. Got this message: "This program cannot be installed on Windows NT version 5.2 or later."

 

i start testing this FWall but i cant not get accesses to my network places, can some help me out please, do i need to create any rule for that?

thanks

 

Hi mata7,
If you are trying to connect to other resources on your network, then you will need to edit 2 rules within the firewall (set to allow).

1) Block winNuke (which blocks filesharing)
2) Stop netBIOS

Only change these to "Allow" if you are on a private LAN, and want to share resources, not if you are connected directly to the Internet

 

Hi,
You may let these rule set to block, but if remote IP is out of the range of your LAN adresses.
Nice firewall I think.

 

has anyone tried this on Vista (32-bit)?

also is this good for p2p/games?

and lastly, anyone try using a (different) LnS ruleset with this firewall?

 

This is interesting....to me anyway. After allowing the firewall to run for 24 hours I checked the memory utilization and was surprised to see that it had dropped...significantly.

After installation it was running at 15K. The latest results are below.

 

Great news for "My pc".

I see where clweb posted on their forum that memory useage was below 10 megs with low cpu ticks as well. Looking better all the time

 

thanks for you help stem

this is what i want to do, i want be able to accesses to my files on my oder computer wish is my HTPC And is connect by wire, and the comp that i have installed the PCTools FWall is wireless, all comp are connect to Internet by netgear fwall router

so if safety for me to do what you say?

hope you understand my English

again thanks

 

I tried this firewall and was not at all impressed. No matter what rules I created, I could not get this firewall to allow my security apps to update, even though they were placed in the trusted applications list. There didn't seem to be any rhyme or reason to this thing, and this coming from a person who used Kerio 2.1.5 so is used to making firewall rules. I also felt the rule-making didn't allow a whole lot of flexibility. I also felt the default rules were too generic and allowed things I didn't care to allow, and I really couldn't refine the rules to my own specifications. Maybe just because it was so different from what I was used to, but I became exasperated with the thing after a very short time and uninstalled it. There are other gripes I had with this firewall, but suffice it to say that, if you're simply looking for a good, free firewall, go with Comodo instead. That's just my own personal opinion, of course.

 

this firewall cannot be installed on vista...

Hi mata7,

As the PC is wireless, you should edit the 2 rules I mentioned, but within the rule place the remote IP, this would either be the IP of your old PC, (if you have this on a fixed IP), or enter your LAN IP with network mask.

If you are unsure how to do this, just ask, and I can post instructions later.

 

It uses LNS cone，I think LNS's advanced rules set can apply on it

 

Hi andylau,
I do not think you would be able to use rules directly from LnS, as the rules are more advanced within LnS, as they include for one example ~TCP flag settings.

 

Just posted an inquiry on the PC Tools forum to confirm the L'nS connection. Hopefully, they'll respond quickly...

Anyone know how to set this up for bittorrent.I am now trying this but having no incoming connections,being reported for utorrent.

 

stem i try to do this be my self and i cant get it work, i will really appreciate if you can guide me on how to do this, if is no problem for you and you can explain me how to do it step be step cause am not so smart Whit comp

thanks in advance

 

Hi mata7,

To edit the rules,
The first one to edit is the "Block WinNuke" rule, to allow the filesharing. Open the firewall, select "Filtering rules", select the "Block WinNuke" rule, then press edit (or a double left click on the rule). You will then get the rules edit window. We need to first add (for this example) you LAN. In my example the LAN is 192.168.123.0.
So in the rules windows,
Step 1: enable the "Remote IP"
Step 2: click on the entry for the remote IP (currently "Undefined")
Then in the popup window, select "Use mask" and enter your LAN, with the same mask as shown.

 

You then o.k. the IP address, and select "Next", you then change the rule to "allow", select next, and you can re-name the rule if you wish.

Repeat this for the "stop netBios" rule

 

Any chance of utorrent please Stem?
