It doesn't support symbolic links at all, deal breaker for me. I can't afford to start duplicating content just because it can't follow a symlink.

Have you tried hard links?

I used to run syncthing...but about 1 year ago (when i started with current employer) they blocked it. i forgot what port it uses, but my employer gave me the ol' wag of the finger for "using an unauthorized app". Funny how dropbox was not blocked but syncthing was.

Welcome to the world where everything except 80/443 is blocked. Sucks but you can still make things work.
