Currently running FSCM 9.2 PUM 51. Looking for guidance on how to enable access outside our firewall for requisition approvals. Have looked into 3rd party products like PathLock, but the cost is prohibitive and it's way more than what we actually need. Back in the day (like 10 years ago), we were using an IIS plugin reverse-proxy thing, but apparently that no longer works with the current PUM we're on. Any information would be greatly appreciated.
