Today I tested my Internet connection using the tests available on the site www.grc.com (ShieldsUp).
I was surprised that the test “common port” failed for the following reason :“Ping Reply: RECEIVED (FAILED) — Your system REPLIED to our Ping (ICMP Echo) requests, making it visible on the Internet.”
On the other side, I noticed also that my Firewall Event logs is empty …
CIS is configure with “Proactive security”
Can somebody give me an explanation about that … Do I have to change my configuration ?
The LAN IP address is 192.168.0.1 (is it the router address ?)
If I type it in my browser, I receive a message saying “Internet explorer can not display this webpage” (free translation because my browser is not in english).
The ping is working.
I can configure my modem using an internet url of my provider.
Find the router address on the vendor’s website or bing (I hate google) it.
Routers usually produce similar results to the results you described. I really wish they would make dropping ping requests a default, as far as I know, you would never have the need to have someone ping your IP.
I had the same thing happen here. I verified that my router had all ports stealthed but still had several ports listed as visible but closed. I tried setting the router to the DMZ mode and 4 less ports showed up as closed even though Comodo was already set in stealth mode. I changed my router back to NAT mode and reset it and the all ports then showed up as stealthed.
then you need to add the wanted port to global rules.
I will show how to add port in firewall with example so don’t add that port!
To open the port TCP 1723 for example
First step is to determine the MAC or Physical address of you network connector. Go to Start → Run → cmd → enter → a black box will show up and enter the following → ipconfig /all (notice the space before /all) → enter → now look up the Physical address and write it down.
Notice that Physical address = MAC address
Firewall → Network Security policy → Global Rules → Add → fill in the following:
Description: Incoming Port
Source address: Any
Destination Address: Choose MAC address and fill in the found MAC/Physical address
Source Port: Any
Destination Port: 1723
Then push Apply → Now make sure that the new rule is somewhere above the basic block rule(s) as the bottom (the block rules have red icons); you can drag and drop the rules → Ok
