Cisco 2600 routing problem

lkfamily 20 years ago

we have a 172.17.8.0/24 network connected to 4006 switch to pix firewall and then to outside through cisco 2600 router this is working fine..

now I am trying to setup a new network 10.190.1.0/24 network with few servers only

I am using cisco 2600 router to route the traffic from 172.17.x.x network to 10.190.1.0 network

I configured fastehernet0 with ip 172.17.8.70 connecting to 4006 switch

next i configured fastethernet1 with ip 10.190.1.2 connecting to a new swictch i enabled ip routing and rip

I connected a laptop to new switch with ip 10.190.1.5

I am able to ping both 172.17.8.70 ( router's e0 ip) and 10.190.1.2 (router's e1 ip)

but i am not able to get pass that and i am not able to see any 172 network or connect to internet I need some help

Hi, who is the default-router of the 172. network(s) and does it have a route to the 10.190. network. Looks like the route backwards does not work. Do a tracert from one of the 172. PC's. The IP addresse that responded last before you only get * * * is probably the one which is lacking of the route to the 10.190. network.

good luck

Here is Senario

Current setup from internet to cisco 2600 router to Pix firewall ( NAting to 172.17.8.0 network) to Cisco 4006 Switch and internal computers are conneted to this SW getting 172.17.8.X IP Addresses this works fine...

Now I am trying to intraduce a second router this router's fastethernet0/0 port is connected to the 4006SW so the IP address of routers fastethernet0/0 is 172.17.8.70

and configured the fastethernet0/1 port of the router to 10.190.1.2 ( I am trying to create a 10.190.1.X network inside) This is what happening now

172.17.8.70 is router's fastethernet0/0 IP address) . I can ping/tracert 10.190.1.2 which is router's fastethernet0/1 IP address but I can not ping any computer's on 10.190.1.X network.

computers and from 10.190.1.X I can not ping any 172.17.8.X computers I need some help
