You will never be able to ping from your PC to linux03. Your config files
describe a network that looks like:
.------.
|router|
---192.168.1 / 24 ----| |=== 192.168.1.120 === LINUX03
| (VM) |
'......'
The problem is that the machines on the 192.168.1 subnet think that
LINUX03 is on the same LAN segment. How do they know that LINUX03 is
"behind" 192.168.1.50? Unless you are going to explicitly tell those
machines that .120 is routed through .50, all attempts by those machines
to find (via ARP) .120 will fail.
If you used a point-to-point link (IUCV, virtual CTC), then VM TCP/IP
could perform Proxy ARP functions to help you, but using a Guest LAN
prevents that.
Without seeing also your Linux IP config, I can't say why Linux03 can't
ping VM TCP/IP.
