[Info-vax] SOLVED: Re: tcpip gateway question

[urbancamo]

Wow, I'm glad I decided to check comp.os.vms as I have the same
problem, but a much simpler context. A hobbyiest network, one subnet,
several machines served their ethernet addresses via dhcp running
under NetBSD. Everything was fine until I installed decnet on the
ZX6000. What's intriging about reading through the previous posts is
the conversation about when the MAC address is changed.

On the ZX6000 I have:

$ tcpip show interface we0/full
 Interface: WE0
   IP_Addr: 192.168.1.57      NETWRK: 255.255.255.0     BRDCST:
192.168.1.255
                       Ethernet_Addr: AA-00-04-00-FB-04    MTU:  1500
     Flags: UP BRDCST NOTRL RUN MCAST SMPX
                                  RECEIVE        SEND

However, if I monitor the DHCP log I get the following as the TCP/IP
stack starts up on OpenVMS:

Oct  2 22:13:16 dell7500 dhcpd: DHCPREQUEST for 192.168.1.230 from
00:30:6e:f3:2c:a5 via ex0: unknown lease 192.168.1.230.

The request fails because I've configured the DHCP server with the MAC
address reported by OpenVMS.

So what's going on here? If I configure DHCP to serve on the hardware
MAC address I get the symptoms where I can telnet/ping any box on the
subnet but *not* the gateway.
