Alright, so I've got a configuration that's basically setup as follows:

R1->R4->R5->Cloud

I've got a host-only network setup on Virtualbox. The IP setup is...

Virtualbox Host Adapter - 192.168.1.1
R5 FE Interface - 192.168.1.254
Virtualbox Host - 192.168.1.11

Now, my machine that's on address 192.168.1.11 can reach all the way to the loopback on the far side of R1 without any problem. However, I can't successfully access that host (ping, FTP, whatever) from R5's FE interface, much less anywhere else in the topology.

What am I missing to allow this traffic to flow?

...and interestingly enough, I've done some captures on the server and the ICMP packets are reaching the server. It's just never sending a reply.

So, still a mystery.

Hi Merijeek,

This really looks like a firewall config issue. Very common on Windows. Disable all firewalls and test again.
