To flush your iptable rules you can run: |
15 |
|
16 |
/sbin/iptables -F |
17 |
|
18 |
-F, --flush [chain] |
19 |
Flush the selected chain (all the chains in the table if none is |
20 |
given). This is equivalent to deleting all the rules one by |
21 |
one. |
22 |
|
23 |
If you only want to flush one chain (e.g. OUTPUT) then run: |
24 |
|
25 |
/sbin/iptables -F OUTPUT |
26 |
|
27 |
Running /sbin/iptables -L -v -n before and after will show you what rules are |
28 |
there and what are deleted. |
29 |
|
30 |
Iptables scripts usually run --flush to clear out any previous rules before |
31 |
they add their own. |
32 |
|
33 |
You can edit any such script to add the MASQUERADE target I suggested |
34 |
previously in the POSTROUTING chain (following the syntax of the particular |
35 |
script). |

... and I bet that the routes do not look like what you posted in your first |

message. |
45 |
|
46 |
Your current routes are not correctly configured. The fact that it is trying |
47 |
to use eth0 may be related to the ethX number? i.e. it starts from the lowest |
48 |
number and it works it's way up. You can delete your net udev rules and |
49 |
reboot to change these (or manually edit your udev rules). Either way, adapt |
50 |
my previous instructions for your respective NIC numbers. |

It looks like a well spec'ed single port modem and ADSL router. Since it is |
59 |
running a DNS repeater you can set in your /etc/resolv.conf files the IP of |
60 |
your router as the DNS server - if it doesn't pick it up on its own. |
