[nv-l] CNAT Configuration qustions

Hi all:
CNAT 1.2 running on AIX 4.3
We have the following test environment:
ROUTER 1 (IP 10.104.193.254)
|
|
-----------------------------------------------------------------------------------
LAN 10.104.193.0
| |
| |
| 10.104.193.249
Netview BOX CNAT BOX (DEFAULT ROUTE to ROUTER 1)
10.104.193.254 10.104.200.1
(DEFAULT ROUTE to ROUTER 1) |
|
|
------------------------------------------------------------------------------------
LAN 10.104.200.0/128
|
|
|
|
ROUTER 2 (10.104.200.126)
|
----------------- (WAN)
|
ROUTER 3 (10.104.200.190)
|
|
------------------------------------------------------------------------------------
LAN 10.104.200.128/192 (CLIENT SIDE)
|
|
MANAGED STATION (10.104.200.189) (DEFAULT ROUTE to
ROUTER 3)
Using the following translation rule:
10.104.201.128 10.104.200.128 255.255.255.192 F F 0
we traslate the managed station IP to 10.104.201.189. We also get the payload
translated. OK!
if we test the following translation rule, we find the same results:
10.104.201.128 10.104.200.128 255.255.255.192 T F 0
Why is the payload traslated, if we have enabled the Passthru FLAG?
Finallly, we would like to know which translations rules are necessary if we
want to
place NAT funcionality on ROUTER 2, and let the CNAT BOX only translate the
payload.
Is enough with the following one?:
10.104.201.128 10.104.200.128 255.255.255.192 F F 1
Any help wolud be very appreciated. I can´t find more information than the CNAT
manual.
Thanks in advance,
Juan Jose Alonso.-
