GitHub user akrasnov-drv added a comment to the discussion: Failures while
assigning public IP via enableStaticNat
I removed all VMs and network and recreated with standard isolated network
offering with static nat with single VR.
Each call execution time was increasing with the last one almost at timeout:

It managed to assign about 40 IPs on the way before failing.
So, there are 2 outcomes from my tests
- redundant VR really doubles (even more) the time of the call
- there is some problem that each next call takes more time (and it depends on
number of calls/assigned IPs, not on some extra load, if I try the call after
some significant time it still fails)
Attaching logs from management and from VR for the time of above.
