Hi, |
| 25 |
|
| 26 |
If I remember correctly, I needed to set |
| 27 |
Networking support -> Networking options -> Network packet filtering |
| 28 |
framework (Netfilter) -> Core Netfilter Configuration -> Netfilter |
| 29 |
connection tracking support |
| 30 |
|
| 31 |
It has been a while though, so it may be another option in the |
| 32 |
netfilter config - just try it :) |
