The Question is: Hello, I have an AlphaServer 4100 with OVMS 6.2-1H3. It runs DECnet IV (nonrouting IV) and UCX V4.1. The configuration includes 2 Ethernet DE500-AA cards. One is configured under DECnet as line EWA-0. Both are configured under UCX as interfaces WE0 and WE1 with different IP addesses (on the same subnet). Everything works fine when any of the cards are accesses via UCX (PING, TRACERT, TELNET or FTP) from a PC located on the same subnet. It also works fine, but only for the WE0 interface, when accessing it from a PC located on a different subnet (i.e. "behind a router"). The problem is that any attempt to access (PING, TRACERT aso) the WE1 interface from a PC located on a different subnet (i.e. "behind a router") fails. The WE0 interface uses the DECnet IV-modified physical Ethernet (MAC) address while the WE1 uses the hardware one. Also, it seems that the first interface to be declared/configured (SET INTERFACE) is the one that becomes "pingable" from another subnet (the one that picks-up the DECnet IV-modified address?). IP forwarding is disabled. I've traced the packets addressed to the second interface (WE1) from a PC located in another subnet, and found they pass the router but no answer is sent by the host software. My first question: is that configuration supposed to work or the two interfaces have to be on different subnets (either hardware implemented via an additional router or software emulated via pseudo-interfaces and interface routing)? And if the answer is "yes, it should work as it is" I would be grateful for any help/advice on solving this issue. Thank you, Mihai The Answer is : First acquire and install the TCP/IP Services for OpenVMS V4.1 ECO kit, or (better) move to V4.2 and the current ECO kit. Then, if the problem persists, please contact the Compaq Customer Support Center directly.
