Bingo you have a reverse lookup failing for the incoming IP address 
192.168.x.x. 
On the client run the command- 
C:\Program files\VERITAS\netbackup\bin:bpclntcmd -ip 192.168.x.x (The actual IP 
address I assume not x's) 

It will fail. Then in the client's host file add that IP and the master server 
hostname. So long as that hostname in defined as a server on the client you 
should be able to connect. If you get a status 59 or 46 then the master server 
hostname is not defined correctly on the client.

Also, I ran again a bpcd command form the client, and I get this:

18:58:41.753 [3328.2604] <16> bpcd peer_hostname: gethostbyaddr failed to 
return peer host, herrno = 0

19:16:30.212 [3876.3880] <16> bpcd main: authentication failed: 17

So it seems taht at one stage, the bpcd connection worked, but fails after! 
(ps: 192.168.0.x is the ip address of the nb master server)

yet, what this error means:
 <8> bpcd peer_hostname: gethostbyaddr failed : The requested name is valid, 
but no data of the requested type was found.

bad dns resolution?
