Can Ping Out but Cannot Ping In 1

[byrne1]

I have my laptop attached to my network via wireless LAN. From my laptop I can ping any machine on my network. But I cannot ping my laptop from any machine on my network. Any ideas?

My laptop is running XP Pro v. 2002 sp 1. TIA!

Did you disable XP's built in firewall?

 

[byrne1]

Yes, I haved checked that the firewall is disabled.

 

[Shekinah]

Are you running a third party firewall such as zone alarm?

 

[byrne1]

No, there is not any third party software running in the background.

 

[Serbtastic]

Are you pinging by name or ip address? Also, exactly what response do you get when trying to ping the laptop?

Post an ipconfig /all output from both the laptop and a machine on your network for comparison.

I've tried both IP address and name but it times out both ways. My IPCONFIG /ALL information is below:

Can you see it in network neighborhood?

 

[byrne1]

Yes I can see it in Network Neighborhood, but when I try to access it it tells me that the device is not accessible - the network path was not found.

Check that the wireless router has not been set to block WAN requests, or that its native SPI firewall does not block ICMP requests.

 

[EddieVenus]

Is the wireless router also a router/firewall?

If it is, is it directly connected to the Internet? either to a cable or DSL type device?

Is your wired LAN plugged into the WAN port on the wireless router?

If it is move that cable to the other ethernet ports, the ones lables LAN or something similar. It sounds like you have yourself "firewalled" from your LAN. You can see it, but it cannot see you. It can see your Netbios name because you are most likely telling it that info through the firewall. Most wireless router/firewalls do not block that by default.

If you are in fact firewalled from your LAN you will need to disable the DHCP function on the wireless device once you connect up to your LAN if you already have DHCP on your LAN. And you most likely would, it is enabled by default on most router/firewalls.

This is an easy one, just move the cable into another spot on the router, disable DHCP on the router, possibly change the IP of the router to match your wired LAN subnet scheme, and release/renew your DHCP lease. It should now show up on your LAN, all wired and wireless together.

Or you could also just set up your wireless router into "router" mode rather than "firewall" mode.

Or again you could also set up your wireless router to make your wireless PC the "DMZ" device. This should pass along all info to it just like if it were in router mode, but it will change the IP like in firewall mode.

Check your vpn settings. I have seen this when the 'stateful firewall' option is checked on the Cisco VPN cliet.

 

[snakyjake]

gpjdiddy...THANKS YOU !!! I've been having the problem too and racking my brains trying to figure it out. I do have Cisco VPN set to "stateful firewall". When I turned it off...it solved my problem!

Amazing!
