Connection to Gateway Failed

[Former Member]

Hello, I am new to working with SAP and I am trying to diagnose and fix an issue that I have with my SAP team not being able to connect to the SAPRouter. Here is what I have so far:

I have a firewall rule in place to allow both TCP and UDP on port 3299 with the source address of 194.39.131.34 and destination 66.21.71.120

Error:

Hi Anthony

You can refer the SAP Note for your issue & configuration in transaction code OSS1

Hi,

First in your OSS1 tcode yous should maintain the local ip of SAP and not the public  ip.

GWHOST=/H/66.21.71.120/S/3299/H/194.39.131.34/S/3299/H/oss001.wdf.sap-ag.de/S/3301,

In your case i can see you have maintained the 66.21.71.120 which is not correct.

Second inform your network team to check the firewal rule, your public ip should be able to communicate with SAP AG ip on port 3299.

Hello Anthony,

ERROR     

partner '66.21.71.120:3299' not reached

I believe SAP Router which is on 66.21.71.120 might be down.

can you check if router is up and running. if it is running fine can you please check if port from server, from which you are checking RFC to SAP Router is open.

Please check and revert back.

Thanks,

Hi,

it looks, that the gateway is reached via two routers. There is problem with  router '66.21.71.120:3299'. Is this up and running?
