PC2 down at the bottom is on network 192.168.0.0 (connected to dg, 192.168.0.1 (router0)
PC4 is connected to router2 ( default gateway, being global address 192.168.3.1 )
My question is why can't I ping PC2 with PC4, and how do I need to configure the relative NAT outside/ inside addresses on the routers in between ( Router1 and Router2) in order to accomplish this feat.
Currently, I can ping (FROM PC4) my both outside and inside addresses configured on Router2 (respectively, 192.168.3.1 and 192.168.1.1 ) with full replies.
I can't ping the addresses on Router1 ( outside / serial facing, address: 192.168.3.2 and downstream-facing: 192.168.0.2 )
So naturally, I can't get a packet from PC4 (subnet: 192.168.1.0; to PC2, subnet: 192.168.0.0 )
The nat configuration on Router2 (inside subnet of, 192.168.1.0 ):
The NAT Configuration on Router1 (between subnet 192.168.3.2 / and subnet 192.168.0.0 [where my LAN I want to ping and PC2 are]
-
I just realized writing this out that seems I'm going between a serial connection, it might be pertinant to have been schooled on how to configure 'Outside Local' and ' Outside'.. if so I might be ahead of myself here because that is definitely not required to know for ICND1 haha.
But, assuming I remedied this by substituting interface se0/0 for a Fast Ethernet connection. Do I still have to have this 3rd/ "extra" subnet of 192.168.3.0 to create a gateway (x.x.3.1) between the routers 1 and 2, even on a fast Ethernet connection?
That's a mouthful. I might take this post in a second, though. It just helps me think to at least sound things out publicly >.<
Solved! Go to Solution.

So I've got it connected to default-G of router 1 now on inside ip 192.168.0.2
I can't ping the outside ip for router 2 (192.168.3.1) but I can ping the inside gateway of fa0/0 for router 2 ( 192.168.1.1), apparently. Is this normal? I thought that address was only reachable from the inside? (PC3 and PC4). I can't ping PC4 yet either.
You will only be able to ping 192.168.3.1 and any networks behind it If router 1&3 are aware of each other networks iAnd to do that you need to use static or dynamic routing

However in your post it shows rtr1 inside ip address as 192.168.0.2 - so pc2 should have a D/G of 192.168.0.2 (router1)
