It can work: your first-level TCPIP needs to have PROXYARP in
ASSORTEDPARMS and the IP address of the secondlevel TCPIP needs to be
coded on the HOME of the first-level TCPIP:
HOME
192.200.2.161 OSA82L
192.200.2.182 LNK00FD
;
(I used such a setup when we got short on OSA ports on a 9672).

If however if the only thing you need is 3270 access to the
secondlevel VM, such a setup isn't required:
- define some virtual 3270's in the config for the secondlevel guest
(using SPECIAL or DEF GRAF)
- ENABLE the addresses in the secondlevel
- on the first-level VM logo, issue "DIAL level2vm"
Even if you have this TCPIP setup, these virtual 3270s remain useful
for cases where TCPIP in the secondlevel system would not start.
