Dear all...

I'm a Chinese and I don't think that my English is well .
But I have a big problem in use IPTABLES .
I've looked all the documents and FAQs , but I can't find a solution to
solve my problem .
At last I decide to ask you in my poor English ...^^||

I have a Linux server (Turbo Linux7.0 in kernel 2.4.9-3) to be my NAT ser=
ver
=2E
I have make it running iptables-1.2.2-6 .
It have 3 NIC(Network interface Card) eth0.eth1.eth2 .
I have 1 LAN and 2 WAN interface they are 192.168.1.0/255.255.255.0 and 2
ADSL (one of my ADSL is pppoe another one is static IP) .
Now I want to bind thy all in my NAT server .
I rty to cut my LAN to 4 part are 192.168.1.0/255.255.255.192 &
192.168.1.64/255.255.255.192 & 192.168.1.128/255.255.255.192 &
192.168.1.192/255.255.255.192 .

That I wish the preceding 3 part go out and in with the pppoe ADSL (ppp0)
and the final part go through with static IP(because they are my servers)=
 .

My biggest problem is in Linux I can't set the default gateway otherwise =
the
ppp0 will not work .
But if ppp0 is working I can't find who to make my final part
(192.168.1.192/26) go through the eth0 out or aome in  ...-.-"

I have do my best to explain my problem .
If you can't understand my question maybe can find somebody who know my
English or can talk in Chinese will better .

Sincerely yours
thanks a lot...^^

I have a Linux server (Turbo Linux7.0 in kernel 2.4.9-3) to be my NAT =
server .
I have make it running iptables-1.2.2-6 .

192.168.1.192/255.255.255.192 .

That I wish the preceding 3 part go out and in with the pppoe ADSL =
(ppp0) and the final part go through with static IP(because they are my =
servers) .

The following diagram would illustrate it quite well if I had any =
artistic talent:

|------------------|
| 192.168.1.0 ~ 63 |----+					   (ppp0)
|------------------|	|	|-----------------------|	|-----------|
			|>......|...........>DHCP (eth2)|-------|ADSL modem |------WAN
|------------------|	|	|			|	|-----------|
|192.168.1.64 ~ 128|----+	|			|
|------------------|	|	|			|	|-----------|
			|	|     61.aa.bb.cc (eth0)|-------|61.aa.bb.cd|------WAN
|------------------|	|	|			|	|-----------|
|192.168.1.129~ 191|----+-------|192.168.1.254	(eth1)	|	  (Gateway)
|------------------|		|-----------------------|		|
					|>.............................>|

|192.168.1.192~ 253|--------------------+
