I can't get through my router (Very Basic).

The below config is on on my 2801s.  For some reason I can seem to ping the inside interface.  I'm connected to a network and I can ping and  But, I can't seem to ping  I know this is very basic.  But, I'm fried and can't figure out why this isn't working.

Thanks in advance.

I was able to get this taken care by statically nating the network on each router.
Are you connected to the internet ok?

Have you tried pinging an address by name, e.g. google.com

This is a closed network.  I'm in a test lab.

from where u r trying to ping ? from network or from network ?

can u show me the output of " show int f0/1"

from the router can u ping the IP of any Node in 172.18.22.x ?

You need a default route on your PC.
If your PC is connected to port 0, then your PC's IP address should be in the range range and your default gateway should be
If your PC is connected to port 1, then your PC's IP address should be in the range, or and your default gateway should be

is there anything connected at interface fa0/1? is the port shutdown? if yes, then you won't be able to ping that interface.

you can check by show ip interface brief.

hope this helps :-)

I need to clarify something.  I didn't want to complicate the situation by explaining my whole config.  I'm pinging this router from another router that is going through a simulator.  Everything is working fine until I get to this router. I can ping the outside interface.  It's just the inside interface.  I can't get to this.
Todd GerbertIT ConsultantCommented:
If whatever you're pinging from doesn't know how to route packets for then you won't be able to ping it.  What does a traceroute to look like?
I'm not intimately familiar with every line in that config you posted, but it appears you're not running any routing protocols, is that correct?
baldy74Author Commented:

Type escape sequence to abort.
Tracing the route to

  1 0 msec 0 msec 0 msec
  2 0 msec 0 msec *

But, the traceroute to is no good.
Todd GerbertIT ConsultantCommented:
Sorry, got the numbers backwards...meant to ask for a traceroute to ;)
And can you post the config for R1?
baldy74Author Commented:

Here is it is.
can u answer my remaining questions ?

from where u r trying to ping ? from network or from network ?

from the router can u ping the IP of any Node in 172.18.22.x ?

baldy74Author Commented:
I'm pinging from the Router that holds as it's outside interface and as it's inside interface.
so from the router itself u cant pinf any nodes in 172.18.22.x ? check whether any firewall enabled   on the PC that u r trying
