I have an network configuration like:
- Ethernet cable from ISP connected to Windows XP machine, configured with static IP 192.168.0.3
- Another ethernet connection from 2nd Windows XP machine's network adapter to a Wi-Fi router (D-Link Airport G+)
- XP set to "Share internet connection", the 2nd adapter configured as static to 220.127.116.11
- D-Link Airport Wi-Fi router also configured as "static connection", it's IP set to 18.104.22.168, default gateway set to 22.214.171.124. Network mask everywhere is 24.
- Laptop computer connected with the router with static IP 126.96.36.199
The problems are:
- XP machine sees the router (it's able to ping it and access it via the web admin tool)
- The router somehow cannot PING the XP machine (using the tool provided by the web-based admin tool)
- The laptop computer cannot ping anything and cannot be pinged
- The router is only accessible when the ethernet cable is connected with a router's 1-4 LAN port, when I connect it via "WAN" port (which I believe is the proper one) it's not visible from the XP machine
If you have similar experience with configuring a network like this I would really appreciate your help. I cannot use the Wi-Fi router with the ISP cable itself.
