Anyone out there who got the new "File Link" feature of Filr 1.1 working in conjunction with activated reverse proxy?

Our system is configured to work with NAM and we added "/ssf/s/readFile/share/*" as public resource and activated File Link in Filr. Now NAM does not request an Login, but Filr does ?!? shouldn't the File Link be public, even when reverse proxy is used?

Any hints/ideas are appreciated.
