			  local host 192.168.10.10, local port 23, and global port 23, create 
			  a new oid natBindProto.192.168.10.23.0.0.0.0.23 and set it to 'tcp', 
			  and natBindAction.192.168.10.23.0.0.0.0.23 and set it to 'create and go'. 
			  Similarly, to delete the static bind, set natBindProto.23.0.0.0.0.23 
			  to 'tcp' and natBindAction.192.168.10.23.0.0.0.0.23 to 'destroy'. 
			  To do this, your mib browser must be able to support multiple
			  variable bindings access.
