allow incoming connections from uss back to zOS

See this idea on ideas.ibm.com

Uss outgoing connection back to zos fails when using host IP.

See the example below, where 10.210.139.54 is IP address of VM that runs zdt.


IBMUSER:/u/ibmuser: >curl -k https://10.210.139.54:10443/zosmf/ -v

* Trying 10.210.139.54:10443...

* TCP_NODELAY set

* connect to 10.210.139.54 port 10443 failed: EDC8128I Connection refused.

* Failed to connect to 10.210.139.54 port 10443: EDC8128I Connection refused.

* Closing connection 0

curl: (7) Failed to connect to 10.210.139.54 port 10443: EDC8128I Connection refused.



When I issue these commands on VM problem is resolved

iptables -A PREROUTING -d 10.210.139.54/32 -p tcp -m multiport ! --dports 22 -j DNAT --to-destination 172.26.1.2

iptables -A POSTROUTING -p tcp -m multiport ! --dports 22 -j MASQUERADE


Can you make these commands a part of the provisioning process?



As a result of this problem is an issue during submission of a JCL that is a part of a zOSMF workflow. Or a PSI installation via zOSMF.
