You need to use virtual machines as routers. Essentially you're trying to establish the following configuration:
Outside world --> OSA on one stack -> TCPIP stack -> Hipersocket -> TCPIP stack --> CTC --> z800 --> TCP stack on z800 If you do this, the two TCPIP stacks connected to the hipersocket are directly connected to the hipersocket, so the prirouter/secrouter/norouter setting no longer matters (they are communicating directly, and both are directly present on the same segment). Don't forget that for this to work, you either need to distribute dynamic routing updates from the TCPIP stack that is attached to the outside world that indicate that it is the gateway to the subnet connecting via the CTC, or insert routing information in the external network routers indicating the same thing before anything outside can reach the z800. ________________________________ From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of Ken Vance Sent: Tuesday, January 30, 2007 11:16 AM To: IBMVM@LISTSERV.UARK.EDU Subject: HiperSocket enabled to forward IP traffic Hi, We have five VM LPARS on our z990. One of these LPARS, LPAR 1, has a CTC to a z800. The CTC is dedicated to the TCPIP running on the LPAR, and it connect to the TCPIP running on the z800. This is an interim solution until we get the z800 OSA connectivity established. I wanted to route all z990 IP traffic destined for the z800 to LPAR 1, and then over to the z800. The only connection from all LPARS to LPAR 1 is a HiperSocket connection. I tried to establish a connection via TCPIP, but I see that there is no option to designate the LPAR 1 hipersocket device as a router. If I was using an OSA card, I would define it as a PRIROUTER. This would enable it to accept other IP addresses and forward them on other links. If I look at the hipersocket link, I see that it is defined as a NonRouter. Is there a way of enabling the hipersocket on LPAR 1 for IP forwarding? Thanks, Ken Vance Amadeus
