WAS 6.40 as single entry point to systems in internal network

Hi,

Can WAS 6.40 be used as a single entry point (i.e only a single URL & single port) from internet to a host of other SAP systems(like CRM, BW, EP) residing in the internal network?

In my case, there is no load balancing required as all the other systems are installed as central instances.

The WAS 6.40 has to map URLs to different SAP systems.

Is it possible?

Thanking you in advance

Best Regards

Meesum.
