RFC error register error in SAP

Hi Team,

I am trying to connect the RFC connection between R3 and portal.

I have created the RFC connection type TCP/IP in R3 with program id

I have updated same program id in portal at destination.

I am getting the following RFC error in R3 and from portal to R3 am connecting fine.

I have updated the following parameter in Portal side

gw/acl_mode = 0

Please let me know how to proceed this

Thanks,
