Negative 1 ping while hosting session in FSX

Hi,

I'm trying to host a session on Flight Simulator X Acceleration. When hosting, however, my server shows up with a -1 (negative 1) ping. No one joins my session because of this.

I have port forwarding on. I am forwarding the following ports:

2300-2400 Protocol = Both
6073 Both
23456 Both

I am also setup as a static ip on my router (192.168.1.102)

DMZ is enabled, and the DMZ host ID is my static ip.

UPnP is enabled.

SBC Global is my ISP

Windows Defender and Windows Firewall is OFF

Norton Internet Security Firewall is OFF

I do not have this problem when I am on my dorm network, only when I am at my parent's house.
If you have any other information you need, please ask.

Thanks!!

This looks like it should behave perfectly.  SBC Global at both addresses?  Wired or wireless?

SBC Global at parents house only.

We had Pavlov Media at my dorm.

Also, at my parents house, I'm wireless.

At my dorm, I was wired.

Thanks for the response!

wireless vs. wired would be my first guess - can you plug into their router?

Plugged into the router and still the same -1 ping result.

There are some issues with FSX on dual core giving this effect but I'm thinking the laptop is the same at the Dorm and at home so let's concentrate on the connection.

You get -1 if the games server gets a very poor or no response to automatically sending ICMP pings to your IP address so is the router stealthed?  

Check the "common ports" scan at GRC: https://www.grc.com/x/ne.dll?bh0bkyd2  If it passes eveything (including True Stealth) then the ping requests are being dropped on arrival.  Can you configure ICMPs (Port 8) to be forwarded to the DMZ machine's address?

The laptop is the same.

I failed the test. Evertything says "Stealth" and "There is NO EVIDENCE WHATSOEVER that a port (or even any computer) exists at this IP address!". All the way down.

Thanks for your help so far! Cant wait to get this fixed.

OK so it looks like we now know what the problem is.

Your parent's router is too good at hiding itself on the Internet!

The default behaviour of most PC's (and routers) is to automatically reflect ping requests from the outside world so when a "ping" is sent to a specific IP address the time and speed of connecton can be determined (it's a kind of Sonar for IT!).

The downside of this is it identifies that there is a computer at that IP address so if you are interested in hacking you can send out a bunch of pings to random IP addresses and everyone that comes back has a computer that could be a potential target.  Firewalls can be configured to simply ignore pings so that the computer doesn't appear to exist.

Gamespy etc reply on ping as a quick & easy way of determining how good a game server is at providing a connection.  It fires loads of ping requests & if all of them come back you get green, most of them get yellow and just a few back get red.  All of these give positive scores.  If none of the pings return then you get a negative score (-1) and red.  According to ping you no longer exist so you are not worth connecting to!

What you need to do is change the firewall settings on the router so that pings are responded to.  You need to let your parents know that this makes them visible on the Net while you are connected as an FSX server (although the actual risk is tiny) and ideally you need to configure the router so that it is hidden as usual once the server goes off-line.

That's the theory.  Now for the practical.  Need to find out how to configure the Linksys.

Back soon ......

Sounds good. I'll standby for instructions on how to configure it to do this. Thanks again for sticking with me and figuring this out.

OK as a quick test try switching off firewall completely & see if:

a) the GRC Shields Up test gives a result that says Pings are being replied to
and/or
b) your FSX ping rating on the server list improves

Then put the firewall back up and post your results

Be aware that yuor network and PCs are potentially vulnerable while the router firewall is down.  You may want to be the only PC connected.

My screen doesn't look exactly like that. Don't have a blanket option to turn off the firewall. I can:

        Block Anonymous Internet Requests
      Filter Multicast (This is on )
      Filter Internet NAT Redirection
      Filter IDENT(Port 113)  (This is on, and grayed out (I can't change it))

Also, I noticed I don't have the latest firmware. Maybe that's why it looks different? Should I upgrade?

If you have anything older than v2.07 then yes do a firmware update.
You could try disabling anonymous Internet requests on your current version but this isn't the same as switching the firewall off.

On the Linksys website, 1.52.5         3/03/2008  is the latest version for my router. I installed this version... is that OK?

My router is "Version 6", and that link is for versions 1-3 or something like that (check version info). Probably should have told you that, sorry.

Then you have the right version.  What options do you have in Firewall after the update?
