That said to ignore packets from everyone!

This modified the default for 192.12.19.20 to allow everything but 
modify, trap and query.

This removed all restrictions from localhost.

Try adding "restrict 192.168.1.0 mask 255.255.255.0".  I'm assuming that 
the client that won't synch with this server has an address of 
192.168.1.x.  This will remove all restrictions for addresses in the 
range 192.168.1.0 to 192.168.1.255 and should solve your problem..
