Here's how I have decided to share my DSL connection..
I take my Cisco 676 external dsl modem/router (internal IP: 10.0.0.1
external: 209.58.xxx.xxx, its one static ip) and I patch its ethernet
crossover cable to my 10/100 hub's uplink port. I then proceed to add my two
machines to the hub, each machine is using IP numbers 10.0.0.2 and 10.0.0.3
respectively, they both use the same netmask and same DNS servers in their
respective configs, their default gateway is set to 10.0.0.1.
Now the only problem I face is when I try to access the internet, only
10.0.0.2 connects fine.. 10.0.0.3 just sits there and does nothing, I can't
even get a ping reply from .03 to either 10.0.0.1 or 10.0.0.2. To make
matters even worse, 10.0.0.2 can't get a ping to 10.0.0.3, but it can for
All network cables are well crimped, well seated, and the corresponding
lights on the hub and modem/router are working fine.. my question is why is
this happening, why just one PC works fine to access the internet but can't
access the LAN, while the other wont even connect to the internet, needless
to say, able to "see" the gateway and the other pc over the LAN.
Is this the right setup to share this? what am I doing wrong? Sorry for all
the questions, I've been searching past posts on this newsgroup for 3 hours
now and nothing seems to help. I am trying to avoid having to buy a hardware
solution, since this modem supports NAT routing.
I beg for a kind soul to help me, any ideas/thoughts are welcome..thanks in
PS: I am beggining to think this has something to do with my CBOS settings,
any proficient Cisco enthusiasts here?
