NAT

[wingu]

Hi.

I'am using NAT.

I'd like to install server inside. Traffic with specific port number from outside have to be connected to inside server.

I opened this ports on access-list. but it's not established.

I think this traffic can't find inside server.

What should I do?

I really hope your advice.

Thanks.

Thank you for your respone.

Sorry, I can't post it.

But I've solved it with "ip nat inside source static" command.

Here I have one more question.

If I used that command, I can make mapping to specific inside server.

But Is there other solution in order to traffic from outside can find inside destination itself?

Thanks.

Hi

Its good to note that you have solved the problem yourself.

There is no solution for this, you need to have the config. done in your router.

U need to configure dynamic nating for this

Hi

I believe that Dynamic NATing is valid only when the first initiation takes from internal network.

In case of servers in internal networks, they do not initiate a connection, the outside network initiates the connection.

Hope that helps.

Pls rate helpful posts.
