I upgraded to 12.1 from 12.06.
I removed the ProxyPass v10/v11 rule from iApp and then deleted the rule.
I backed up the device using the archive.
I upgraded to 12.1.
I restored the configuration
I installed the ProxyPass Rule v10/v11. I had two issues with lines 250 and 486. To resolve the issue, I created two blank data groups with strings, ProxyPassSNATs, and ProxyPassSSLProfiles.
I then added the ProxyPass rule back into the iApp and it seems to be working.
Thanks for providing this code!
Thanks,
Alex
