If you want a connection, from a SAPgui to an R/3 System for example, to run through a SAProuter, then you need to enter the route in the SAPgui command line.
You can use SAProuter if there is no direct IP connection between the communication partners. SAProuter must be running on a host that is connected to both IP networks. It can then receive data from the SAPgui in one IP network and relay it to the R/3 server in another IP network, and vice versa. Normal IP routing is used between the application programs and the SAProuters.
Connections established using SAProuter have the additional
advantage that no end-to-end connections between the participating system
are necessary on network level. For example, if accessing a frontend PC
on an R/3 server with an intermediate SAProuter, it is not necessary to
define the complete path between the two systems at TCP/IP level. It is
sufficient if both parties can reach the SAProuter. From
an SAP communication viewpoint, this represents a point of concentration
in your network that serves as a starting point for each subconnection.
Each subnetwork stored logically behind a SAProuter is therefore reduced to the network address of the SAProuter.
Without SAProuter, the Internet Protocol (IP) addresses must be unique, which cannot always be guaranteed, particularly on international networks.
With SAProuter it is possible to connect two points that
have unofficial,or even identical, IP addresses. Therefore, it is rarely
necessary to adapt existing address topologies using
official IP addresses.
SAP Online Service & Support now only supports SAProuter
connections due to these advantages. Because SAP routes all accesses to
internal systems (such as SAPNet - R/3 Frontend) and all service connections
via SAProuter, the connection between SAP and the customer is reduced to
a single SAProuter - SAProuter connection.
How can I check what is my sap router version?
Go to saprouter directory in command prompt cd :\usr\sap\saprouter
> type saprouter -v
You can see result like below
