Internet Connection Sharing + Networking

Hi,

I have a small home network (two P.C.'s connected through
a hub). Up until recently, I had networked these using
static I.P. addresses and that worked fine.

They had been connecting to the Internet using a dial up
account (there was a 56k modem in each computer.)

I recently purchased an ADSL modem, and connected it up to
one of the P.C.'s. I then installed Internet Connection
Sharing.

The Internet Connection has shared successfully, but I am
no longer able to browse my home network. I have tried
both dynamic and static I.P. addresses on the client
machine, but the problem still remains.

The ICS host (192.168.0.1) can ping the client
(192.168.0.2). The client can access the Internet, but it
cannot ping the ICS host.

Can anybody help???

Thanks in advance,

John

Since the host can ping the client and the client has Internet access,
we know that the TCP/IP protocol and the network hardware are working
right.

The most likely problem is that a firewall on the host is blocking
access from the client. Some recent antivirus programs include a
firewall component.

Can the host access the client using either of these commands in the
Start | Run box, substituting the actual name of the client computer?

\\192.168.0.2
\\client

If only the first one works, there's a problem with NetBIOS name
resolution. If both work, it again suggests that a firewall on the
host is the problem.

Hi Steve,

Thanks for your help. I've tried both of those but neither
works. Norton Personal Firewall is installed on the host
so I'll look into that configuration. Is there any
particular process/.exe that I should allow that may be
blocked???

Cheers,

John
