Hi all,
I have a copied of my prod DC and a few servers onto esx5 host which i have created an isolated vswitch(no nic assigned). In addition all lab vms on the isolated vswitch has no default gateway assigned (blank) only ip address. Safety measure . I will explain shortly... all is good so far ....but to access vms on isolated vswitch i need to connect to vcenter console to vms . This is ok but very slow cumbersome and sluggish 
...
i was thinking about creating a vm lets call it my rdp server that i will rdp onto from prod then from this vm i will rdp onto lab vms on isolated network . configuration for rdp server as follows.
I assigned 2 nics to the rdp server ( one connect to prod network vswitch and other to isolated vswitch) ,now my question is this safe? meaning in no way I want my test lab vms on isolated vswitch to connect to prod servers , this woulkd be a nightmere. As a test I am unable to ping prod servers from lab vms , and I didn’t expect to . remember as precaution I am not using a gatewate on lab vms and I can only ping the rdp server ...so far so good
please let me know thoughts or perhaps someone has set this up in the past , ...
Thanks
