SAPgui disconnection problem

We are having a problem with clients disconnecting from the SAPgui. They are attempting to connect to a Solaris/Unix server through a firewall. We have found that the connection to the Wintel server is fine, but not the UNIX server. Clients on the local network (no firewall) are also fine.

We are having a problem with clients disconnecting from the SAPgui. They are attempting to connect to a Solaris/Unix server through a firewall. We have found that the connection to the Wintel server is fine, but not the UNIX server. Clients on the local network (no firewall) are also fine. We receive the error:

NiPRead: recv (131: Connection reset by peer) [niuxi.c 928]

You should probably install SAPRouter (see http://service.sap.com/saprouter). It redirects incoming SAPGUI connections to the correct SAP systems. It has many connection and security configuration settings (see the online documentation for more information). SAPRouter listens by default to port 3299. You will have to open this port on your firewall.
