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 192.168.1.1 and 192.168.1.2.  But, I can't seem to ping 172.18.22.19.  I know this is very basic.  But, I'm fried and can't figure out why this isn't working.

Thanks in advance.

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.

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 192.168.1.3-192.168.1.254 range and your default gateway should be 192.168.1.2.
If your PC is connected to port 1, then your PC's IP address should be in the range 172.18.22.1-172.18.22.18, or 172.18.22.20-172.18.22.254 and your default gateway should be 172.18.22.19.

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.

If whatever you're pinging from doesn't know how to route packets for 172.18.22.0/24 then you won't be able to ping it.  What does a traceroute to 192.168.1.2 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?

R1#traceroute 192.168.1.2

Type escape sequence to abort.
Tracing the route to 192.168.1.2

  1 10.10.10.1 0 msec 0 msec 0 msec
  2 192.168.1.2 0 msec 0 msec *

But, the traceroute to 172.18.22.19 is no good.

I'm pinging from the Router that holds 10.10.10.2 as it's outside interface and 172.18.22.20 as it's inside interface.

I was able to get this taken care by statically nating the network on each router.
