Ping to Honeyd virtual host replying Destination Host Unreachable

I have installed and am running honeyd and farpd successfully on Ubuntu 13.10. But, now the problem is:

Pinging the virtual host from honeyd host (and from any other local network machine)

ping IP_virtual_host

Output: Destination host unreachable

So, I took the following steps to try to find the problem:

1) #nmap IP_virtual_host Output: Host seems down. But, it's not really down. S, I ran it with -Pn option. 2) #nmap -Pn IP_virtual host Output: Host is up. All 1000 ports scanned are filtered. So, I checked the ports from blocking. 3) I flushed the iptables and created new rules allowing all incoming and outgoing traffic from honeyd host and virtual hosts. There is no hardware firewall. 4) Added "set template_name tcp/udp/icmp default action open" to honeyd.conf file for both virtual router and virtual hosts (all open only for the time being). So, router rules also allow ICMP traffic.

After taking all these steps, I am still getting destination host unreachable on pinging my virtual hosts from honeyd host and local machines. And nmap is still giving output as mentioned in steps 1 and 2.

I am stuck after hours of searching and reading. Please feel free to point out my mistakes. Thanks in advance.

Looks like a routing problem to me?.. Posting 'ifconfig -a; route -n; sysctl net.ipv4.ip_forward; iptables-save' on the host, your (f)arpd and honeyd configuration and any log or stdout/stderr output may be a start.
