[pca] Proxy/relay question

[Tim Hosfelt]

In my environment I have networks separated by firewalls.  In network A I
have successfully set up a PCA Patch server via proxy and all hosts on
network A can update via PCA.  In network B I have no access to a proxy
server, but my network team did open port 8888 through the firewall for a
single host - is there a way to set up the single host on network B to
relay requests to the PCA Patch server in network A?
