Hi Victor,

Try to understand your question: is this about something like root_proxy variable? Since you have done a proxy setup so I suppose your question is not about if and how for setting up a proxy. I don't think we currently have this. But I think you can request such a feature to be implemented. In the mean time, I am doing similar things at SLAC by manipulating the NAT table in iptables (modify TCP head so that traffic to host A is sent to host B, etc.)

regards,
