Hi Jason,
did you try to use a traceroute (unix) / tracert (windows) to destination.
194.39.131.34 is sapserv2
10.1.2.17 is your saprouter ?
Are both hosts reachable ?
Did you check OSS Note http://service.sap.com/sap/support/notes/2000132
The saprouter can be enabled with a trace file
To enable it, please check Additional Options - SAProuter - SAP Library
Hope this gives you some hints where to search
Best regards,
Matthias
