Hi. I have a 2514 router, 2 hubs, and 2 other
routers (1602 and 2502). The 2514 has 2 serial
interfaces, and 2 ethernet interfaces.
Basically, I have two questions:
1. You know how if you are not on the same subnet you
cannot even ping the router? How come you can telnet
from home into remote sites? I dont really understand
this, at all. I have 3 pcs at home (though, all
old...). The routers ip address is 192.168.0.1 on e0,
and e1 is 172.16.3.1. Shouldnt i be able to ping the
class b address from the class a address router? Or
telnet into it from a different subnet? If not, how
come on somehting like firewallking.com we can access
any router? I dont understnad that!
2. How can I simulate two networks. Such as,
assuming one router is in Chicago, and the other in
NYC. Can I do that within the vicinity of my house?
Or am i reaching? I was thinking, just assign them to
different subnets, and basically that is that. But we
have to deal iwth accesslists, protocols, and the
frame relay simulation, right?
Thanks, and Id really appreciated comments on this. A
lot of newbies are in the same boat....
