Hi Andy (et al.), A quick question. What are the options offered by xrootd for deployment or configuration when all data servers are behind a firewall which blocks all direct access by clients on an external network? Section 4.2 of the configuration documentation<https://xrootd.slac.stanford.edu/doc/dev55/xrd_config.htm#_Toc88513970> seems to suggest a proxy server would be necessary in this case. Is that correct? If so, what exactly does this proxy server do, and how is it set up? Thanks, Al ________________________________________________ Albert L.
