Hi, I have 2 computers hooked up to through a hub to the ADSL modem, the
company has assigned me 2 IPs , but they are different in their network id,
one is 205.250.75.x, other one is 205.250.200.x. Before, when i was using
ICS, i can share teh printer among these 2 computers, now when i use HUB, the
IPs are different, i can nolonger use printer sharing, nor see each computer
through the network computers, and they have all been set to same workgroup.
how do i work around this? without using a hub?!
Your computers have individual public IP addresses, which makes it
very hard to allow them to share files and printers with each other
while blocking access by Internet hackers.
Do you need individual public IP addresses? If not, a setup using a
single public IP address shared by ICS or a broadband router is more
secure and easier to set up. If possible, I recommend replacing the
hub with a broadband router.
If you want to keep using the hub and two public IP addresses, keep
reading.
Make sure that both computers have firewalls -- either XP's built-in
firewall, or a firewall program from Norton, McAfee, ZoneAlarm,
Sygate, etc. Configure the firewall to block all access, allowing no
exceptions.
The broadband modem-and-hub setup is described in the Windows XP Help
and Support program. Click Start | Help and Support, search for the
topic "Network configurations overview", and look at the section
labeled "Individual Internet connections".
The solution given there is to install the IPX/SPX protocol for file
sharing and to disable file sharing on TCP/IP. I've written a web
page showing how to do it:
Windows XP Network Protocols
http://www.practicallynetworked.com/sharing/xp/network_protocols.htm
There are two reasons to use IPX/SPX instead of TCP/IP for file
sharing:
1. Since your DSL provider assigns public IP addresses in different
subnets to your computers, it isn't possible for them to communicate
with each other using TCP/IP.
2.Those public IP addresses are accessible by everyone on the
Internet. Using TCP/IP for file sharing could let other people access
your shared files.
