router issue

Former Member — Thu, 15 Jan 2009 13:35:45 GMT

Hi All,

We have ECC 6.0 with Oracle db on WINDOWS OS. We have installed SAP Router and have also applied the SNC license. I am able to successfully do a test connection to SAPOSS rfc thro sm59. Now, the issue is that when i try to connect to my SAP (from a remote location ) thro router string it says "Route permission denied (x ip address to y ip address sapdp01)"

X ip address is the ip address of our firewall

y ip address is the ip address of our sap server.

I thought that the issue could be in the hardware firewall, but the network guy says that he created a rule and allowed all the access.

In my routtab file I have given incoming access to all the ip address.

Many Thanks,

Balakrishnan.

Check the saprouter logfile - it will tell you what configuration in the saprouter is missing.

Hi,

The error is coming from the saprouter itself so this does not have anything to do with Firewall.

Could you paste here your saprouttab file to try to help you out?

Hi,

The SAPROUTTAB file should not have P * * * entry, in case of SNC connection this entry will not support.

The entries should more specific to the sap server you want to access.

Pls find below the sample SAPROUTTAB file

#SNC-connection to SAP

KT "p:CN=sapserv2, OU=SAProuter, O=SAP, C=DE"

#SNC-connection from SAP to local

KP "p:CN=sapserv2, OU=SAProuter, O=SAP, C=DE"

#Access from your local Network

P * 194.39.131.34 3299

#All other connections will be

P * 192.168.100.21 32xx

D * * *

Hope it helps

Regards

Hi Bala,

If this is new install, have you tried to open a connection from Service Market place to your system and has SAP been successful in connecting to your system? Please try that.

Please configure your saprout tab to permit access from outside network to internal ip address on port 32xx.

Thanks

Mikir

Allowing access from local network to SAP through all port (instance) 
P * 194.39.131.34 3299 
P 192.168.0.10 194.39.131.34 3299

This lines are not necesary as per your first line starting with KT you are telling the saprouter to allow all access from your saprouter going to sapserv2 in any port so you should delete this lines.

If you are going to allow connections using sapgui to your internal sap servers then you should use:

P (incoming IP or * for all) (target IP SAP server) (instance port)

At this time you are allowing only connections from a to SAP service, no sapgui connection is allowed that's why sm59 is working fine.

To do a connection insert a line like this:

P * 192.168.x.x 3200

P ( * or source IP) (IP for a SAP server in your LAN) (the port for that SAP instance)

Then try to do a connection and you will be fine.

Good Luck

Hi BAla,

Ensure that you make the following changes in routtab file:

P <local ip address> 194.39.131.34 <your instance no.> . for eg P 192.168.168.168 194.39.131.34 *
