Network Topology Question

[redbrickhat]

I have 3 computers A, B, C.

A is connected to a wireless router which connects to a cable modem.
The wireless router has an IP address of 192.168.0.1, the NIC card in
computer A has the address 192.168.0.2.

B has a wireless card with address 192.168.0.3 which can access the
Internet through A's wireless router. B also has an Ethernet card with
address 169.254.0.1 connected to an Ethernet switch.

C has an Ethernet card with address 169.254.0.2 which is also connected
to the Ethernet switch.

Questions:

1) Is there any way for C to access the Internet? Could I change the
routing tables in B and C so that packets are forwarded to the wireless
router at 192.168.0.1?


2) From B, I can ping 192.168.0.1 but can't ping 192.168.0.2. Also,
from A, I can ping 192.168.0.1. but can't ping 192.168.0.3. Can I add
these addresses to the routing tables so I can ping them?


Thank you.

Thank you.

so connect the switch to the router ...turn off DHCP on the switch(if it has
it)

Re 1):

C can access the Internet if:

1. You bridge the connections on B; or

2. You enable routing on B, manually configure TCP/IP on B and C's Ethernet
cards, give C a default gateway of 169.254.0.1 and a DNS server IP of
192.168.0.1, and configure a static route on the router; or

3. Change the IP scheme on the router to something other that 192.168.0.x
and enable ICS on B's wireless adapter.

Re 2) - check your firewall and/or third party security software settings.
