Need help in Basic Routing

[hfakoor222]

I am doing a tutorial on PAT translations and have come up against a routing issue.

I can ping the outside facing PAT router from my hosts, but I can not reach the other end of the segment to the WWW. router which is on the same subnet of the PAT outside facing interface.

I've turned IP routing off and have managed to ping the outside facing PAT which is on a different subnet from my hosts ~ In effect the PAT translations are working but I would like to know how to reach the other end of the segment

Here is the Topology and CLI outputs

Both Alice and Emma can reach 192.168.34.3 when I turn off IP routing. They cannot ping .34.4 which is at the other end of the segment.

Any suggestions on creating an IP route 

I've already tried 

creating a few different routes on PAT with little success

Return traffic from www to your host,

Check route in www router.

I just created a OSPF network and it seems to be working.

Alice(config)#ip routing
Alice(config)#router ospf 100
Alice(config-router)#network 192.168.123.0 0.0.0.255

Would there be a way to create IP routes on individual segments rather than using a routing protocol? I believe static routes would be more secure in this respect, however I could not get my topology to work with static routes

[MHM Cisco World]

Static route need in both dirrction, dont forget that.

Also static route need to be for global  pat ip since local ip is hidden by pat.

If PAT Router holding Layer 3 Gateway for both IP subnet and ip routing enable, they should be able to reach each other ?

can you post from PAT router the below information :

show run 

show ip interface brief

show ip route

show ip arp

Make sure below Router need to have default route point to respected gateway

emma and alice 

ip route 0.0.0.0 0.0.0.0 192.168.123.3

on www

ip route 0.0.0.0 0.0.0.0 192.168.34.3
