Restrict Access of NW 7.01 AS Java HTTP Port to specific IP address

Dear Expert,

I would like to define a HTTP Port on a NW 7.01 AS Java that is only accessible from one specific source IP address. Only that specific IP address should be able to access the AS Java via HTTP. All other clients should access the system via HTTPS.

I searched the SCN, Help and SAP Notes, but I could not find any useful information that it is even possible. I know that for NW7.3 AS Java it is possible, but that's not the version we got.

Do you know how to configure the HTTP port on a NW 7.01 AS Java to only accept calls from one source IP?

Thanks a lot for your help.
