Hi,
Can you make sure your SNC is configured correctly. I see error
If above is fine can you create routab with below replace your IP at highlighted text.
# SNC connection to and from SAP
KT "p:CN=sapserv2, OU=SAProuter, O=SAP, C=DE" 194.39.131.34 *
# SNC-connection from SAP to local system for R/3-Support
KP "p:CN=sapserv2, OU=SAProuter, O=SAP, C=DE" <SAP Router Internal IP> 3299
# Access from your local Network to SAP
P 10.*.*.* 194.39.131.34 3299
P 172.*.*.* 194.39.131.34 3299
Thanks
