Wanting to play around with OpenFiler, I figured I'd install it in a KVM. Here's what my home lab looks like:

Problem is: While I can ping from the OpenFiler VM to an outside public IP and I can also ping my home PC (192.168.100.4), I can't for some reason ping the openfiler VM from my home PC (i.e.: I can't connect to it's admin interface)


- iptables on openfiler is empty and all default policies are set to allow
- ip forwarding is enabled on the KVM host. the forward chain on the host has a blanket ACCEPT statement for src 0.0.0.0 dst 0.0.0.0
- I have a route on my home PC for the 192.168.100.0 network as shown in the diagram
- Nothing in /etc/hosts.deny or /etc/hosts.allow on openfiler


TIA

Is ip forwarding enabled in the /etc/sysctl.conf file?

With all due respect: did you read my problem description or even have a look at my diagram? My guess would be no I found the problem: I got curious so I started a continuous ping from my home PC and started tcpdump on the VM and noticed while I was getting a ping reply on the home PC, I wasn't seeing anything in tcpdump. I had a look at the routing table again on the home PC and noticed that the 192.168.100.0/24 network had my local NIC as it's gateway. After a few minutes I realized that my adapter on the home PC (for some reason) had the IP 192.168.100.3 IP assigned to it. God knows why or when I did that.. it obviously caused problems. Once the IP was removed, pings were getting through.

Thank you for posting the solution (it will help future people that may have the same problem)

Maybe next time you post the solution, you can forgo the insult to someone who is taking the time to help you

Sorry you took it the wrong way, you're obviously very sensitive to what people tell you. When I started my sentence with "with all due respect", I really did mean it. I was just a little shocked you didn't clue to the fact IP forwarding was enabled based on 3 different hints:

1. My diagram clearly shows IP forwarding is enabled (not only is it marked on the diagram but it's written in red instead of black lettering)
2. My problem description clearly explains IP Forwarding is enabled. Here's what I said word for word "ip forwarding is enabled on the KVM host. the forward chain on the host has a blanket ACCEPT statement for src 0.0.0.0 dst 0.0.0.0"
3. Maybe less obvious, but I did also clearly state pings work one way (from OpenFiler VM to home PC) just not the other way.
