Ok I did the configuration however, PC1 is not able to ping PC2. But from PC1 I am able to ping the gateway of PC2 . Same goes for PC2. Each PC is able to ping there own gateway however they cannot ping each other. What am I doing wrong. Below is a copy of the switch config.

Thank You,

Is the ip addressing in your diagram correct?
PC1 172.16.0.2
Default gateway 172.16.0.1
PC1 connected to switchport 4 or 7
Router Eth0/1 = 172.16.0.1
routing is enabled on the router
Router is connected wo switchport 4 or 7

PC2 192.168.0.2
default gateway 192.168.0.1
PC1 connected to which switchport?
Router Eth0/0 192.168.0.1
Connected to which switchport?

Can you ping either PC from the router console?
Are both router interfaces UP/UP ?

ASKER

On www.virgoletta.com I put up an updated version of how the network currently is. Both interfaces on the Router are up. However, the only PC from the router using the console port I can only ping PC2. I am not able to ping PC1.

Can you post the results of "show vlan brief" and "show int status" on the switch?

ASKER

Here it is.
Thank You,
vreyesii

And you're saying that from the router you can ping PC2 but not PC1?

Can PC1 ping 172.16.0.1?

ASKER

Yes that is what I am saying. From PC1 I tried pinging 172.16.0.1 and I was not able too.

Thank You,
vreyesii

Can you post result from the router of "show ip int brief" ?

ASKER

Here is the output for the Router.

New_York#sh ip int brief
Interface IP-Address OK? Method Status Prot
ocol
Ethernet0/0 192.168.10.1 YES manual up up

Serial0/0 5.0.2.1 YES manual down down

Ethernet0/1 172.16.0.1 YES manual up up

New_York#

And from the router console you cannot ping the pc 172.16.0.2 . . .
Is there any firewall software on that PC that could possibly be blocking ICMP?

This one's a head scratcher.....!!!
Are you sure the cables are good?

ASKER

Ok I rebooted PC1 and now I able to ping 172.16.0.1 however PC1 cannot ping 192.168.10.2 which is PC 2 but PC1 can ping 192.168.10.1.

thank you,
vreyesii

OK that looks like progress. Now post result of "C:\>route print" from PC2
Any Firewall sofware on PC2?

ASKER

I got it working. What I did was that I enabled routing on the New York router. Now from PC1 I am able to ping PC2 and vice versa. However, I thought I did not have to enable routing on the New York router?

thank you,
vreyesii

Of course you have to enable routing any time you have different ip subnets on different interfaces and you want to route between them...

ASKER

why didn't donjohnston in his configuration mention anything about that?

thank you,
vreyesii

Probably because routing is usually turned on by default and we don't normally think about it?

Unless you're running a VERY old IOS version, the only way ip routing could be disabled is if someone issued the command "no ip routing". We just assumed that it was enabled.
