About a month ago I posted this to the AIX370 list.  We still haven't
resolved the problem and while talking to Proteon they suggested that
I post it here.

HELP!!!

I'm having problems getting the following cluster configuration to work:

Here is the output from a VM NETSTAT GATE command:
VM TCP/IP Netstat R1.2.2
Known gateways:

I am getting the following messages on the TCPIP machine on VM.

ProcessIpOptions: bad option: 32
ProcessIpOptions: bad option: 129
ProcessIpOptions: bad option: 32
ProcessIpOptions: bad option: 129
(This is repeated over and over)



This is the error message coming out on the p_4200 router console:

ip.038: pkt 129.81.32.2 -> 129.81.128.62 prt 91 no srvr

I can see traffic on the 128 subnet from 129.81.132.32 (zulu) to
129.81.32.2 (aixdev) packet length 96 type 91 and I see traffic from
129.81.32.2 (aixdev) to 129.81.128.62 (p4200) same packet length and
type.

I can succesfully telnet to aixdev from machines on both the 128 subnet
and the 132 subnet.  ANyone have any ideas as to what I might have
wrong?  Any help would be greatly appreciated.

Thanks in advance,

John/

Update:  We have been able to get the cluster up if we put the PS/2
on the VM side of the router (packets do not go through the Proteon)
but not if the packets go through the proteon.
