Hi,
I am having a strange issue. Strange because I have set this lab up at my colleges network and had no problems. Packet tracer also is ok... I'm starting to think that there is a problem with the router.
Topology screenshot attached
Basically I have PC-A Connected to a 2960 Switch
Switch connected to a 2811 Router
The 2800 Router connected to PC-B
So 2 end devices and 1 router with 1 switch.
IP addresses have been configured to the ports on the router.
Switch is clean.
Local Firewalls off both PC's
I can ping from router to both PC's and the other way
Both PC's ping to interfaces directly.(But not interface other side)
Router Ip info below...
Router#show ip interface brief
Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 192.168.0.1 YES manual up up
FastEthernet0/1 192.168.1.1 YES manual up up

Hello,
is your 'real' router a 2811 as well ? What happens if you take the switch out of the topology and connect both PCs directly to the router ?

Hi,
Sorry I missed this reply. :(
Yes, the router is the same one. I also have just bought a 2821 which is what I am working on right now. I have tested without the switch with the same results.

Hi,
Please attach your topology (PT file).

Hi @kimoak75 ,
I insist that the problem can be the firewall of some PC or some rule of the firewall. I suggest you check this.
Regards
