How to allow networked computer internet access through another?

[David Ellis]

Two computers connected via crossover-cable ethernet. Both
running XP SP2 with account names and passwords. Each can
access the other's resources. Static IP addresses assigned.

Computer A has recently been connected to a wireless network
that uses DHCP to assign the IP address whenever computer A
logs on. Bye bye static IP address. Computer B can no longer
ping Computer A, even when using computer A's dynamically
assigned IP address. Computer A can still ping B.

How do I get computer B to "see" computer A while A is
connected to the wireless network?

David,

Asymmetrical access / visibility is generally caused by a misconfigured or
overlooked personal firewall, but there can be other causes.

David,

Having now seen your prior post, where you request information about using ICS
or another solution to share your WiFi based Internet service, makes me wonder
whether your problem is connected with a previous attempt to make that work.

I do not know what the unsecured WiFi network is, but I'll bet that however it
works, you will have to address the connection, sharing of the connection, and
Windows Networking setup, as one integrated topic.

May I suggest that you post your query in one thread only, and explicitly close
the other thread. Post a third time, replying to ONE of your 2 posts, saying
"This thread is now closed". You may otherwise get conflicting advice, that
will cause both threads to continue, fruitlessly.

Chuck, thanks for helping this network neophyte. I'll start
again because I've learned a few things since the posting
and I'm reading the document you recommended in the other
thread.

David,

My pleasure. Networking is a lot of fun, but it can be frustrating too. You
have an interesting task, because you want to network 2 computers, and provide
Internet access to them both, using it would appear an external WiFi router that
you authenticate thru your browser.

We'll be here as soon as you have more questions.
