Hello all-
I was hoping someone could stop me from banging my head on the desk
any further...
I have two Redhat 7.2 (2.4.9-17) guests on a guest LAN, setup by our
VM SysProg, both images cannot reach outside the GLAN. I have ifconfig'd
them with the proper ip, netmask and mtu, and I have set the default route
in the machines to the correct ip, along with defining the dev to be used
for the gateway and the netmask for the route as well (the network address
was calculated from the ip and netmask, and was already correct in the
routing table).
I can see and exchange between the two linux boxes and everyone else
on the GLAN, I can talk to the router (a VM TCPIP stack that owns an
external card). One of the boxes has an initial ctc connection, if that is
used as the default route interface (different subnet, different router,
etc), then I can reach the GLAN interface from outside the GLAN, but the
packets route back through the default interface.
Here is where I am: I have re-configged the interfaces on the linux
boxes at least eight times, and our poor SysProg has looked at his routing
config at least as much, at one point, we did have to define his ip as able
to route within the OSA card (?), but that is no longer an issue.
I'm at my wits end, to my knowledge, I can only do so much to make the
interfaces work on the Linux side, they are in /proc/chandev, the
/etc/chandev.conf file is set, I have even echo'd the arguments in to the
proc file, and I can see the devices and config them, even use them, but
only on the same subnet. Whenever I try to ping out, I get a "Network is
unreachable" error, and when I try to ping in, it just times out (unless
the above condition of the separate default interface is there). So I am
lost, the routing setup looks good, and my interfaces are set correctly, I
will include output below, any ideas?
