This is not an issue I have presently but is a record of a solution that worked for me, today, for future searchers. This post will hopefully save time for anyone that has this problem now or in the future.
I was unable to download patch h2014.05.27.0000.0000g. The error message was 'Unable to download patch files. [30413] [25008] [20495]'. The error appeared at random points near 470MB. I succeeded in downloading 6 patch files before this.
I tried the following steps: Close all background applications. Disable all security software. Clear cache. Delete download folder in My Games. Uninstall FFXIV and try again.
None of these attempts worked. What DID work was retrying the download through a free VPN. I downloaded just this one file, canceled on the next one to switch off the VPN, and resumed downloading normally. I am not done patching, but I have encountered no issues since.
This is, as others have suggested, either a routing or port issue. By using a VPN, a different route is used and (I believe) port forwarding becomes a non-issue.
Other things that worked for others, which I did not try: Waiting and trying again later. Switching from Wireless to Wired.

Some people have contacted tech support, but I have found no remarks of positive outcomes. This may simply be a failure to return to the conversation once their issue was resolved.
