A first firewall server application, FWP1(P)-FWP5(P), on a first network address translation node, NATP1(P)-NATP5(P), is associated with a similar second firewall server application, FWP1(B)-FWP5(B), on a second network address translation node, NATP1(B)-NATP5(B), separate from the first network address translation node. The first and second firewall server applications form a second load sharing group server application, LSG3. The second load sharing group server application receives VoIP traffic ...
