Hi! Its been a long time since I last came here… nice sorting out in the forums… anyway, I was wondering if it was perfectly ok for CPF to work side by side with Windows Firewall, or will the two have comflicts? So far, I have not been having problems, and I do not feel secured if windows firewall is off. In fact, is it alright to switch windows firewall off?
Also, I was wondering how much will my surfing speed slow down if I was to enable ‘Packet Checksum vertification’. (I’m on a 512 kbps Broadband connection)???
Last question would be, I am having a huge amount of medium’ warnings of ‘Access Denied’ in the logs. Should I be concerned?
Based on other users posts, CPF runs well with XPs Firewall.
Do you need XPs Firewall? No.
Should you feel safe with XPs Firewall? No, I wouldn’t.

I don’t know, it will have an impact… but, no idea to what degree. But, there’s one way to find out. Try it & report back. ;D

Post some examples. You can export CPFs log to an HTML file & then cut ‘n’ paste some examples from there.
ok… I tested the packet vertification thingy. Speed difference was not visible at all, but using a tweak in mozilla, the speed difference was 0.2 secnds for google.com , so I guess I’ll leave it on. ;D

Destination: 1x.1x4.6x.22x:2962
Reason: The packet has an invalid TCP checksum value
The above was just taken. This happened a few minutes after I enabled the packet thingy. (50 OVER ALERTS of the same thing!) Should I start worrying? The X represents a number.

Er… Pass. But, based on the message… it is obviously something to do with the Packet Checksum Verification option. Is it a problem? I don’t know. Who’s the foreign IP? Someone you know? What was the source port?
this is the medium alert that I keep getting. Anything wrong or unusual?
Again, it depends on who 16x.21.13x.1x is & the frequency. But, not a major problem. Somebody or something is trying something that CPF is not allowing. It’s normally only a problem if something is not working as a consequence.
I’ve seen quite a few ICMP related messages that are sourced by my DNS. These can be safely ignored.
