extendable static NAT

Hi,

I am having trouble with NAT configured with 'extendable' option...I have two separate domains and created a translation to my inside servers, both translate to the same server address (SMTP)

illustration example

ip nat inside source static tcp 10.11.11.14 25 60.10.19.194 25 extendable

ip nat inside source static tcp 10.11.11.14 25 60.10.19.197 25 extendable

When the first translation is created, the second never happens unless I remove the confi line that is not working and configure it back. Then it works fine.

Please, I need help as for what might be the reason...I don't really understand it.

Re: extendable static NAT

When you have one-to-one mapping, you can work without extendable keyword. You should only be worried about incoming emails. See if you can use ip instead of tcp.

Hope this helps.
