problem with nat and global

hello,

i have a problem with a mailserver. here is my configuration.

global (outside) 1 x.x.102.227

nat (inside) 0 access-list noNAT

nat (inside) 1 192.168.100.0 255.255.252.0 0 0

nat (inside) 1 192.168.112.0 255.255.252.0 0 0

nat (inside) 1 192.168.120.0 255.255.252.0 0 0

nat (inside) 1 192.168.124.0 255.255.252.0 0 0

nat (inside) 1 192.168.132.0 255.255.252.0 0 0

nat (inside) 1 192.168.136.0 255.255.252.0 0 0

nat (inside) 1 192.168.140.0 255.255.252.0 0 0

nat (inside) 1 192.168.148.0 255.255.252.0 0 0

nat (inside) 1 192.168.164.0 255.255.252.0 0 0

static (inside,outside) tcp x.x.102.228 www 192.168.100.140 www netmask 255.255.255.255 200 200

static (inside,outside) x.x.102.229 192.168.100.76 netmask 255.255.255.255 0 0

static (inside,outside) x.x.102.230 192.168.100.238 netmask 255.255.255.255 0 0

this configuration works fine, but we have some problems with customers with reverse dns and with a record.

so we have to change the configuration. the mailserver with the ip 192.168.100.140 will now translated to the global ip x.x.102.228

I have added the two config lines

global (outside) 2 x.x.102.228

nat (inside) 2 192.168.100.140 255.255.255.255 0 0

i have also cleared the translation table (clear xlate)

and I want to translate the outgoing sessions from 192.168.100.140 to x.x.102.228.

If I add this two lines, I can not connect from the mailserver to the internet.

PIX Version 6.3(1)

Any ideas ??

Hi,

You are creating overlaps within your translations (looking at the following parts on your config)

nat (inside) 0 access-list noNAT

nat (inside) 1 192.168.100.0 255.255.252.0 0 0

nat (inside) 2 192.168.100.140 255.255.255.255 0 0

I woudl use nat-id 1 instead of 2 for the specific translation and nat-id 2 for the more global translation (where you are now using 1)

Hope this helps and kind regards,

Leo

hi leo,

I have changed the nat id's. But no success.

I have updated the software to 6.3(3) and now it works.
