I'd try first with iptables filters *disabled*, to make sure it's not a |
| 8 |
firewall issue. Once it works, enable packet filtering (if you need it). |
| 9 |
But until you are sure it works, make sure nothing prevents traffic |
| 10 |
flow, so disable iptables filters. |

It means that, if you want ip forwarding, you have to enable it manually |
| 17 |
using the command |
| 18 |
|
| 19 |
echo 1 > /proc/sys/net/ipv4/ip_forward |
| 20 |
|
| 21 |
To verify that forwarding is working, simply do |
| 22 |
|
| 23 |
cat /proc/sys/net/ipv4/ip_forward |
| 24 |
|
| 25 |
and it should print "1". |
| 26 |
Keep in mind that if you reboot, you have to re-enable forwarding if you |
| 27 |
want it again. |
| 28 |
|
| 29 |
Finally, run a network analyzer like wireshark and see for yourself |
| 30 |
what's happening. I'd look at ARP packets first: make sure ARP is |
| 31 |
working correctly. |
