Connecting to external IP of internal server

cgossett

I was just wondering if it's possible with an ASA 5510 to connect to the external IP address of an internal server from inside the network.  I have already set up dns doctoring for dns lookups, and everything is working fine there.  We have an application inside the network that tries to connect straight to the external Ip of another internal server.  If it is possible, could I get directions on where to look in the ASDM 6.4?

Hello Chase,

It is possible and you have 2 options:

a) If you are using an external DNS use the DNS doctoring

b) Do a U-turning setup.

I will be more than glad to help you but using the CLI as it will be faster and easier.

I will need to have the private Ip address of the Internal server and the public server

Any other question.. Sure,. Just rate all of my answers.

Regards.

Thanks for the reply, Julio.  I was actually able to configure the software to connect using the internal IP so the problem is solved.
