Ping problem?

[aefstathiou41]

In packet tracer my wireless laptop can ping other PC's in the network but PC's cannot ping the laptop.

This is the IP of laptop (192.168.200.100) and I am pinging from the PC.

Hello,

post the Packet Tracer project file (rename the .pkt to .jpg otherwise you cannot upload)...

[aefstathiou41]

When I rename it it shows me that

<The contents of the attachment doesn't match its file type.>

[Georg Pauwen]

Are you renaming the file in Explorer ?

[aefstathiou41]

Yes

[Georg Pauwen]

What does your topology look like ? Post the configs of the devices you have in your network...

[aefstathiou41]

At the first post I have post the topology in jpg file

Hello,

where do you announce or redistribute into OSPF the networks 192.168.100.0/24 and 192.168.200.0/24 ? How is the wireless router connected to your network ?

[aefstathiou41]

I think I am not announce them. That could probably be the problem? The wireless router is connected through the switch that is connected on the router (R3). The wireless laptop can ping everything the problem is the vise versa. 

[Georg Pauwen]

Hello,

on R3, configure two static routes and redistribute them into OSPF:

R3

ip route 192.168.100.0 255.255.255.0 GigabitEthernet0/1
ip route 192.168.200.0 255.255.255.0 GigabitEthernet0/1

!

router ospf 1
redistribute static

Hello,

can you post the output of 'show ip route' from R3 ?

Maybe you can use a free file sharing program such as Dropbox to send the file...
