BigFix Firewall protocol traffic

I got a request from the customer as "Is it possible to setup BigFix in a way that the Relay
server always establish network sessions with the BigFix Client?
Alternatively, is it possible to have two Relay servers in each Slave
zone: for TCP traffic (Client to Relay) and one for UDP (Relay to
Client)? "

Anyone please tell me is it possible to implement the Relay as requested ?
