If you can ping VM from VSE and ping VSE from VM, then the connection is
fine.
Since the other VSE systems can access outside of VM and you LAN type
can access the other VSE systems, the VM connection and routing is
fine.
So it is a possible routing problem for that VSE.
If, from a LAN you try to ping the VSE, if a ping message (SET
PING_MESSAGE=ON in your IPCONFIG), then the LAN can reach the VSE, but
VSE can't get back out. If no ping message appears on the console, then
the routing problem is from the LAN to VSE.
If you do get the ping message, then the dirty way is to put a DEFINE
ROUTE in your IPCONFIG specifying the GATEWAY of your VM ip address.
That should fix that.
If you don't get the ping message, then take a look at the VM side.
You might have a mismatch of IP address specified in VSE vs VM.
Also watch out for subnetting. If you subnetting changed, the
non-working VSE, might now be on another network.
Hopefully others will chime in with better stuff, but it is 5 PM CDT so
you may have to rely on people to the "west"<G>.

I find that I'm always stumbling around when it comes to
understanding the configuration and use of TCP/IP in VM.
We have three VSE virtual machines which use TCP/IP in VM as their
gateway, connected via virtual ctca's. The IP stacks are working
correctly in two of the guests, but not in the third. It previously
worked and no changes have been made. I can see nothing wrong from
the guest's point-of-view. It comes up as if full IP connectivity is
there, but it's not reachable from the outside nor can it reach the
outside. This suggests to me that the connection between VSE and VM
is working fine but that the gateway function in VM TCP/IP is down
for this one IP address. I can't easily bounce the VM TCP/IP machine
because others are using it.
There must be some diagnostic commands to help figure out what's
going on, but when I look at the TCP/IP Planning and Customization
Manual I'm not finding them. How can I proceed?
We're on z/vm 4.2.
- Tom.
