XP Can be Pinged, But XP can't Ping

[dax 0]

My Unix machine can ping my XP no problem,

But when I try to ping my Unix box from XP... Nothing.

Any Idea where to start looking?

It's a Simple network setup

Unix 199.199.199.5

XP 199.199.199.6

The XP, under connection status has no default gateway, and is connected

The xp also has an other network card, so i disabled that connection incase it was causing the problem.

Any direction would be great. Thank you

Some obvious things to check:

 

Subnet mask set correctly on the XP machine? (eg. 255.255.255.0)

Some kind of firewall running on the Unix machine? (might be deliberately set to block pings)

I got a Question. 199.199.199.* on and internal network? I've never seen that range used before. You learn something new all the time.

 

try one of these instead.

10.0.0.0 — 10.255.255.255

169.254.0.0 — 169.254.255.255

172.16.0.0 — 172.31.255.255

192.168.0.0 — 192.168.255.255

I use 100.100.100.100 and 100.100.100.200 for my w98 / XP,Linux machine. I know 192.*.*.* is what is recomended to use but my network runs with no problems. What can go wrong if you use other internal network addresses. Does it harm anyone or can it interfere with the internet. For example what if I use 216.239.35.100 (Google) will it interfere?

This is exactly the reason. If your IP address happens to be the same on your LAN as a site on the Internet and your LAN is connected to the Internet (NAT, ICS etc) then you (and anyone else on the same LAN) will be unable to reach the Internet site.

In fact, due to the way subnetting works, you'd be unable to access any computer on the Internet with an IP in the range 100.100.100.0 - 100.100.100.255 ("best case scenario" assuming a subnet mask of 255.255.255.0).

The IP ranges Captwista mentioned are reserved for Local Area Networks and so will be guaranteed never to cause such a conflict.
