Peculiar ping problem

[richardkathitu]

I have three routers, connected in series, as shown in the attached picture:

 R3->R2->R1->Mintbox(emulated pc)

All routers have eigrp configured, all routes advertised.

The problem is, I can't ping the pc from either R3 or R2. However, pc can ping all of them, and R2 can ping the pc.

Where could the problem be?

Mintbox pc has default-route 192.168.0.1

Also, routing table on all routers shows the 192.168.0.0/24 subnet present

My first guess would be a local firewall on Mintbox1.

I thought so too, but R2 can ping Mintbox1. Any more thoughts?

Which router can ping the PC ie. R1 or R2 (you changed between posts).

From R3 can you ping 192.168.0.1 ?

Sorry, made a typo as I posted the original question, fixed. it. R2 can ping the pc. 

I've fired up GNS3 right now to try, and it works, apparently. Don't know what caused it in the first place.

Thanks though for the assist.
