Firewall

[roy]

Hi all,
I'm new to this group & on my second day trying to wireless network 2
computers. Do I need a firewall on both computers? I am not using a
router as my primary computer has access to the net via broadband and is not
switched off.

When I fired up the Safecom wireless USB on my second computer (no modem),
the firewall immediately asked for permission for items to have access to
the net. I was surprised to see that saying yes to that firewall allowed
access even though my connection went through the second computer. My
simple brain tells me that both firewalls should ask for the same
permissions.

Secondly does anyone know of a known problem with Safecoms 54Mbps 802.11b/g
Wireless LAN USB 2.0 Adapter.
When I install the software onto my second computer (Windows ME) it sees the
adapter & works OK. When I re-boot the computer it no longer sees it. I
have to remove it via system/device manager then plug it back in again. I
have looked on their web site for updated software with nothing found. The
box says that it is compatible with Windows ME.

Any help would be very much appreciated.
Regards,
Roy.

The computer on which you run a communications program prompts you for
permission to allow that program to communicate. This is to prevent trojan
horses from making outbound connections to their masters.

The ICS computers does not know what program you are running on some other
computer. It can only see what TCP or UDP port numbers are being used, and
when the connection initiation is inbound or outbound. For outbound
connections, all ports are generally permitted unless explicitly denied in
the configuration.
