As result Nanoprobe and two other checks www. Security and seccheck. The latter, at first attempt, showed port pptp open, so I redirected that port too to a local deadlock. As yet I could connect to all desired servers inclusive E-mail and News without slow downs. Similar Artilces: Port stealth Nanoprobe found my port closed, not stealthed. I ran accross some posts which indicated that I should try port forwarding with my router.
That stealthed port , but now nanoprobe reports I am sending returning unsolicited probes! I assume this is my router. I forwarded to Also, was ZAP 3.
I have my internet zone set to max. I just got a new router, installed it, and ran with GRC port stealth tests. I followed GRC's directions as best I could, but can't get it to stealth port What's the trick?
Port is not stealthed. Can anyone tell me what I have to do to stealth this port. What gives here? This is starting to piss me off. Stealth port ? Reply Reply as topic. This topic has been deleted.
Only users with topic management privileges can see it. Can it be done? You cannot "stealth" an open port. You can either allow connections on it, or block the traffic, but you have to choose.
Just forward it to an unused ip on your network. Triggering snowflakes one by one.. The trouble experienced by most security conscious people, is that port can sometimes be rather tricky to stealth. As we know, NAT routers double as terrific hardware firewalls due to their natural tendency to drop all incoming unsolicited packets, thus stealthing their owner's networks. But since stealthing port can "theoretically" cause connection problems but probably never does NAT routers usually treat port specially.
They deliberately return a "closed" status, actively rejecting connection attempts. New users of NAT routers, who use this site to check their security, are often disappointed to discover a single closed blue port floating in a calm sea of stealth green. The good news is. The trick is to use the router's own "port forwarding" configuration options to forward just port into the wild blue yonder.
Just tell the router to forward port packets to a completely non-existent IP address, one way up at the end of your router's internal address range. The router will then NOT return a port closed status. It will simply forward the port packet "nowhere". So the Linksys routers will give you the best of both worlds. Bravo Linksys! While I agree that stealth is silly, some people think it is important, and the guy deserved an answer, not a philosophy. I don't have a router, so I couldn't answer the question.
With any luck, a D-Link owner will jump in. Closed ports are closed, and so are "stealth" ports, so don't worry about it Lars M. Hansen www. On 26 Jul , jonasxy web.
Konnt ihr mich sehen? Konnt ihr mich fuhlen? Ich versteh euch nicht. Mine can assign Notice that the first 3 octets are fixed i. I use It is unimportant what port you specify for that virtual server host because it doesn't exist, anyway, so I just reuse Basically this is used to open a port to a host through the router's firewall but you are pointing it to a host that can never exist because the DHCP server in the NAT router will never be able to assign that IP address.
When you next run GRC's stealth test you will then see port never gets responded to as opposed to immediately returning a status of closed which also declares that something exists to announce that status.
Not responding to a connection attempt is different than returning a status of closed. One doesn't reveal that there is anything at the other end. The other obviously must require something to exist to report back the closed status. Sure the hacker might go away if they find all the attempted ports are closed but they'll still know you exist. No response means the hacker won't know if your network doesn't exist or if it is powered down. I'd rather leave them in the dark and possible avoid later intrusion attempts.
For those that argue that stealthing a port by not responding to a connect attempt is no better protection than immediately and actively reporting a closed status on the port, I argue that if stealthing doesn't hurt and might help then there's no point not to do it. Share with others. One solution could be to forward port to either: a A computer with a desktop firewall that "stealths" the port, or b to a non-existing IP address on the LAN.
I think the point that some of us are trying to make is that there's little point in chasing the pie in the sky. Jbob is correct; a "stealth" device will slow down port scanning, as the scanner will have to wait for a timeout rather than just getting a quick "we're closed" response and move on.
It does not, however, make the target less visible as implied by the mo inker Hhm Hhm. Well, but what does wild blue yonder and one way up at the end of Hansen badnews hansenonline.

For the small user in which 'stealth' seems to be important for some people it really does not add that much. The time cost will be minimal. Now, for larger enterprise level systems, the difference between rejection and drop can be significant.
